Cammalleri's five-year-old daughter, Chloe, was dealing with a severe case of pneumonia that required surgery, the veteran forward told reporters Wednesday, including Chris Ryan of NJ.com.
She is now home after the successful procedure.
"It's your worst nightmare," Cammalleri said. "We're fortunate she's going to make a full recovery and I appreciate everybody's support."
He flew home before the Devils' game against the Buffalo Sabres on Nov. 11, when Chloe was hospitalized.
Cammalleri said the club was fully supportive of him and immediately gave the go-ahead to be with her.
Forward Kris Versteeg is set to return to the lineup after missing nine games with a groin injury, the team announced Wednesday.
Versteeg has battled inconsistency when healthy this season, recording four points in 12 games. His struggles mirror those of the Flames, which are looking to find the win column after posting a 8-12-1 record through their first 21 contests.
"The guys have been really going pretty good here for the last five, six games," Versteeg said in a statement. "Obviously the record not being what we wanted but 3-2 in the last five is a positive. It's something to build on."
Austin Lemieux, son of former NHL superstar Mario, will join the NCAA's Arizona State Sun Devils next season, reports Craig Morgan of Arizona Sports, citing sources.
The 20-year-old currently plays for the Islanders Hockey Club of the U.S. Premier Hockey League. He spent last season with the USHL's Omaha Lancers, scoring 14 points in 57 games, and has previously participated in Pittsburgh Penguins prospect camp.
Austin will join many NHL bloodlines who make their hockey life in the Grand Canyon State, with Max Domi, Ryan MacInnis, and Henrik Samuelsson - all sons of former NHLers - all part of the nearby Arizona Coyotes organization.
After months of speculation, the NHL knighted its 31st franchise Tuesday, as it unveiled the Vegas Golden Knights.
In the end, franchise owner Bill Foley, a graduate of the U.S. Military Academy, couldn't move away from a name similar to that of his alma mater, the Black Knights.
As for some of the other names that were considered?
"I liked Nighthawks, we had that name. I liked Desert Hawks. I kind of liked Sidewinders," Foley told Nicholas J. Cotsonika of NHL.com. "But I wanted a name that was more team-oriented and being about the warrior class, which is what hockey players are."
Vegas also considered other variations of the Knights name.
"Silver Knights was an option because this is the Silver State, but Nevada is the largest gold producer in the country," Foley told Case Keefer of the Las Vegas Sun. "Gold is a precious metal, the No. 1 metal versus silver. I didn't feel Desert Knights had character to it."
As for the Golden Knights logo, according to the Sun, the original concept featured a knight in armor, then shifted to a knight on horseback, before ultimately deciding on the knight helmet logo.
"It was almost unanimous. (Golden Knights) was almost everyone's favorite," said Vegas GM George McPhee. "When we pushed names around in meetings, they asked me what I thought of Golden Knights, and I said, 'That's my favorite.'"

Here is a look at the Squad Up daily NHL fantasy picture for Wednesday, November 23:
Triple Threat
LW Alex Ovechkin (71K), C Evgeny Kuznetsov (54K), D John Carlson (37K), Capitals (vs. Blues): The Blues are one of four teams playing the second half of a back-to-back Tuesday. They came out of Boston with a 4-2 victory, but G Jake Allen faced 41 shots, likely setting up backup Carter Hutton with Wednesday's start. He has allowed seven goals over his past two starts.
LW Tanner Pearson (60K), C Tyler Toffoli (70K), D Jake Muzzin (34K), Kings (vs. Islanders):Toffoli and Muzzin offer pivots from the more expensive Jeff Carter and Drew Doughty, respectively, who are listed at the same position. Pearson and Toffoli skate on the top line at 5v5 and on the power play. Muzzin is on the top PP and will avoid Islanders C John Tavares at 5v5.
LW Evander Kane (49K), C Johan Larsson (26K), RW Kyle Okposo (62K), Sabres (vs. Red Wings): The Red Wings have announced G Jimmy Howard as Wednesday's starter. After a phenomenal start to the season, he has allowed three or more goals in two of his past three starts. Should C Ryan O'Reilly (oblique) return from injury, sub him in for Larsson.
Goalie Breakdown
TARGET - Sergei Bobrovsky (113K), Blue Jackets (vs. Flames): Bobrovsky has allowed just five goals over his past three starts. He hasn't faced more than 27 shots on goal over the same span, as the Blue Jackets' team defense appears to be improving. The Flames average just 7.26 Scoring Chances per 60 minutes of 5v5, per Corsica.Hockey.
BARGAIN - Jhonas Enroth (76K), Maple Leafs (at Devils): The Devils average just 5.90 Scoring Chances per 60 of 5v5, the lowest number in the league. Much of the season average was boosted by LW Taylor Hall, who remains sidelined by injury. The Maple Leafs played Tuesday night, so G Frederik Andersen may be given the night off.
FADE - Mike Smith (102K), Coyotes (vs. Canucks): Smith is tied as the highest-priced goaltender on Squad Up's late slate. He has stopped 65 of 69 shots on goal since his return from injury. The salary is more indicative of the matchup against Vancouver's impotent offense. While averaging just 2.11 goals per game on the season, they've scored at least three in three of four games.
CONTRARIAN - Cory Schneider (100K), Devils (vs. Maple Leafs): The Maple Leafs average more goals per 60 than any team in the league, and their Expected Goals For of 3.15 is also tops in the league. They will be playing the second half of a back-to-back, after losing 2-1 at home to the Carolina Hurricanes Tuesday.
Bargain Plays
LW Carl Hagelin (30K), Penguins (at Rangers): Hagelin has followed up last season's breakout with just six points through his first 19 games played. He has recently joined C Sidney Crosby on the Penguins' top line, offering some hope following a brief demotion to L3. The improved situation has come with a rise in ice time. He has topped 19 minutes in each of his past two games.
C Christian Dvorak (25K), Coyotes (vs. Canucks): Centering the Coyotes' second line, Dvorak has a quality matchup against a Canucks team with only one efficient line. Dvorak's ice time has dipped in his past two games, but he still managed three SOG in two of those contests.
D Oscar Klefbom (31K), Oilers (at Avalanche): Klefbom has scored in three consecutive games, and he added an assist in his most recent game. The scoring surge can't be expected to continue, but he can remain involved in the offense while playing over 22 minutes per game.
Top Fades
C Travis Zajac (50K), Devils (vs. Maple Leafs): Centering the Devils' top line at 5v5, Zajac lost much of his appeal when Taylor Hall befell injury. He has gone without a point in five consecutive games, registering just two SOG over his past three. He'll go head-to-head with Maple Leafs C Auston Matthews.
LW Jonathan Drouin (50K), Lightning (vs. Flyers): Drouin has a goal and an assist in his past three games, twice topping 17 minutes. He remains primarily in a defensive role while playing with C Valtteri Filppula and RW Ryan Callahan. He'll likely spend much of his night matched up against the Flyers top line centered by Claude Giroux.
RW Marian Hossa (39K), Blackhawks (at Sharks): Hossa has been held to just a single shot on goal in four of 11 games this month. He has eight goals in those 11 outings, clearly unsustainable production. He played a season-low 14:37 in Chicago's 5-0 loss to the Oilers Monday.
Contrarian Options
D Victor Hedman (44K), Lightning (vs. Flyers): Hedman hasn't scored since Nov. 5, but he has topped 23 minutes in each of his past six games. He's an even bigger piece of the top power-play unit in C Steven Stamkos' continued absence, and he'll face the 23rd-ranked penalty kill of the Flyers.
C Mikael Granlund (43K), Wild (vs. Jets): Not often thought of as a top offensive play, Granlund has four goals and 10 points on the year. He has topped 18 minutes in three consecutive games, playing on the right side of Minnesota's top line. The Jets allow 3.27 goals per road game, the 10th-highest rate in the league.
C Leon Draisaitl (49K), Oilers (at Avalanche): Draisaitl has been dropped to the Oilers' third line in an effort to increase production from Ws Anton Slepyshev and Zack Kassian. His ice time has remained consistent, and he has six points in the Oilers' past four games. He'll exploit Colorado's lack of depth beyond the top six.
Brent Burns is off the market, but that doesn't mean there won't be other attractive blue-liners that could be available come July.
When the free-agency pool opens, alongside general managers' wallets, a host of top-notch defenders could be up for grabs. Here are five defensemen to keep your eye on next summer:
Kevin Shattenkirk
St. Louis Blues defenseman Kevin Shattenkirk is the cream of the crop, and the best available option after Burns re-upped in San Jose.
With free agency as a possible end game, Shattenkirk is off to a career year, already with 14 points in 20 games. His previous high-water mark was 45 points in 2013-14. A smooth puck-handler, Shattenkirk has been incredibly consistent in recent years, averaging 44 points over the last three seasons - he finished with 44 points in 2014-15 despite an injury limiting him to 56 games. The 27-year-old is due for a nice raise on his current ticket, an affordable $4.25 million AAV.
At 37 years old, the lifetime member of the Montreal Canadiens surely isn't showing his age, off to a career year this season. With 17 points in 20 games, Markov is on pace to shatter his previous best, when he put up 64 points during the 2008-09 season. Markov still logs big minutes, averaging 21:57 this season. In the twilight of his career, it's also likely Markov will be more willing to accept a cap-friendly deal, down from his current $5.75 million AAV.
Karl Alzner
There aren't many better than Washington Capitals defender Karl Alzner, who combines a strong shutdown game with good mobility and puck-handling skills.
Alzner isn't known for his offensive game - he's never scored more than 21 points - but gets his work done at the other end of the ice. Averaging 20:11 this season, Alzner solidifies the Capitals' top four blue-liners. Given his unique skill set, and the barren of players of a similar ilk likely available via free agency, the 28-year-old will no doubt see a significant pay increase from his current $2.8 million AAV.
Michael Stone
Arizona Coyotes defenseman Michael Stone had a breakout year in 2015-16, finishing with 36 points, with 30 assists among them. Unfortunately, a significant knee injury late in the season led to a summer of rehab and a one-year extension with the Coyotes for the then-restricted free agent. That pushes Stone toward unrestricted free agency next summer.
A built defenseman at 6-foot-3 and 210 pounds, Stone has been among the league leaders in hits and blocked shots. His booming shot is also an asset on the power play. Stone, 26, will be among the youngest defenders available next summer and will likely be looking for a long-term extension that pays close to his current $4 million AAV.
Trevor Daley
Trevor Daley brings a unique characteristic to the market: a Stanley Cup ring. Winning the Holy Grail with the Pittsburgh Penguins last season, Daley has a winning pedigree, desirable to many teams looking for that last piece to push them into the winner's circle.
A veteran defender, the 33-year-old Daley is like many new-age defenders entering the league - undersized, but a quality puck-mover. With seven points in 19 games this season, Daley is nothing if not consistent - he's averaged 30 points over the past three seasons. For a team looking to round out their top four defensemen, Daley would be a notable addition. Currently signed to a $3.3 million AAV, an extension in Pittsburgh could be too much for the team's cap picture.
Vegas' big unveiling wasn't without an unexpected victim.
The University of Central Florida, which went from using Golden Knights to Knights as its team nickname in 2007, tried to make that clear after the NHL's newest expansion franchise announced Tuesday night that it was adopting the former.
The school's athletics department changed its Twitter bio to further emphasize the point.
