Kadri was given a five-minute charging major and a game misconduct for hitting Wingels in the numbers and into the boards midway through the third period.
In its video explanation, the NHL's Department of Player Safety said Kadri drove "recklessly into the defenseless Wingels, causing his head to dangerously impact the boards."
The Tampa Bay Lightning clinched top spot in the Eastern Conference and the Atlantic Division title as a result, and they will face the New Jersey Devils in the opening round.
The Bruins will have home-ice advantage against the Leafs, while the Lightning host the Devils in Game 1. Both series start on Thursday at 7 p.m. ET.
Saturday night's heavy slate of games didn't determine every Stanley Cup playoff series, but it did decide most of them.
Six of the eight matchups were set in stone on the penultimate night of the NHL regular season.
All that's left to be settled is the Atlantic Division, which will come into focus depending on what happens in Sunday's game between the Boston Bruins and the Florida Panthers.
Here's what we do know:
Eastern Conference
Metropolitan Division
Washington Capitals (M1) vs. Columbus Blue Jackets (WC1)
The division-winning Capitals get the Blue Jackets, who finished a single point and one regulation-or-overtime win behind the Philadelphia Flyers, who grabbed third place.
Pittsburgh Penguins (M2) vs. Philadelphia Flyers (M3)
This one should be an absolute dandy, as the Battle of Pennsylvania will once again be brought to the playoff stage.
Western Conference
Central Division
Nashville Predators (C1) vs. Colorado Avalanche (WC2)
We've known about this matchup since Thursday, but it should be a terrific series between two foes who aren't too far apart geographically.
Pacific Division
Vegas Golden Knights (P1) vs. Los Angeles Kings (WC1)
Ready for Vegas and Hollywood in the same playoff series? The expansion darlings will make their first forray into the postseason, and they'll do so against a Kings team that is back in the dance after missing out in 2016-17.
Anaheim Ducks (P2) vs. San Jose Sharks (P3)
Two perennially competitive rival clubs will meet in the other Pacific Division matchup when the Ducks meet the Sharks. San Jose went on a tear down the stretch to climb the standings, while the Ducks occupied second place for much of the season.
The circumstances of the modern era deserve a bit of the credit, but the Toronto Maple Leafs set a couple of impressive franchise marks Saturday night nonetheless.
Toronto also set a new franchise record for points in a season (105), surpassing the previous record of 103 that was set in 2003-04.
The club finished the regular season at 49-26-7, earning seven points by virtue of losses in overtime or the shootout.
Andersen has been excellent for much of this season, but this wins record (and the fact that it was previously co-held by Andrew Raycroft) is largely a product of the modern era's elimination of ties in favor of the shootout that has increased the number of wins and losses across the league.
On Wednesday, the league's players association published the findings of its annual poll, in which more than 500 players answered a slew of hockey-related questions.
Most of the questions elicited unsurprising responses, but there were a handful of interesting results:
Carey Price gets included among all-time greats
There's no denying the Montreal Canadiens goaltender has had a terrific career to this point, or that he's one of - if not the - best active netminders, but Price got a bit too much love in this survey. Here's how 361 players voted when asked who they believe is the best goalie of all time:
Player
Percent
Patrick Roy
39.3
Martin Brodeur
33.2
Dominik Hasek
13.6
Carey Price
3
Ken Dryden
3
Somehow, Roberto Luongo didn't make the top five despite ranking fourth all time in wins and sitting in the top 10 in save percentage. Also, where were Jacques Plante, Terry Sawchuk, and Ed Belfour?
Chalk it up to recency bias and the respect players around the league have for Price, but it still didn't make much sense.
Overwhelming support for the current point system
When asked whether they like the way points are awarded for a win or a loss in the regular season, the players reached a clear consensus, with 77.7 percent support among the 412 who answered.
That's somewhat surprising, considering the "loser point" (the awarding of a single point for an overtime or shootout loss) has plenty of critics in hockey circles and is arguably a major reason for the increase in parity in the NHL standings.
The fact that Wes McCauley received the most votes when the players were asked to name the best referee wasn't a shock, but Peel somehow garnered 4.4 percent support among 113 players, finishing third behind only McCauley and Kelly Sutherland.
Peel is without a doubt the NHL's most controversial official. He has a lengthy history of blown calls, and who could forget his interview with Yahoo Sports' Greg Wyshynski that was conducted at a bar and got Peel suspended?
Perhaps it's simply a matter of name recognition, but clearly other referees were more deserving.
Ott's coaching prospects better than Ruff's
Steve Ott might be more popular behind the bench than he was as a player.
The former pest and current St. Louis Blues assistant coach got 5.1 percent of the votes among the 216 players who answered when asked which current assistant coach should be the next head coach.
D.J. Smith of the Toronto Maple Leafs (first with 8.3 percent), Todd Reirden of the Washington Capitals (second with 7.4 percent), and Ulf Samuelsson of the Chicago Blackhawks all finished ahead of Ott, but the fact that he got more support than longtime NHL bench boss Lindy Ruff (fifth with 4.2 percent) was a bit of a head-scratcher.
They really, really like Peter Forsberg
NHL players love them some Foppa.
Peter Forsberg got the most votes among the 379 players who replied when they were asked to name their favorite player growing up (8.4 percent, edging out Steve Yzerman at 8.2).
More alarmingly, though, 2.3 percent - or the fifth-highest total - of 388 players responded with Forsberg's name when asked to pick the best forward of all time.
Sure, the Colorado Avalanche legend was a terrific player, albeit in a career cut short by injuries, and yes, most of the players made more reasonable choices (Wayne Gretzky, Mario Lemieux, Sidney Crosby, and Jaromir Jagr rounded out the top four) but the fact that Forsberg was mentioned before the likes of Gordie Howe, Bobby Orr, Maurice "Rocket" Richard, and Mark Messier made it clear that some of the current players could use a history lesson.
Wind or no wind, the show will go on as scheduled.
Saturday night's Stadium Series game between the Washington Capitals and the Toronto Maple Leafs at Navy-Marine Corps Memorial Stadium in Annapolis, Md., will begin at the original start time of 8 p.m. ET, the NHL confirmed in the afternoon.
There's been some concern about windy conditions there this week. Friday's practices that were originally intended to be outdoors were moved inside and to other locations, and neither team took part in a morning skate on the open-air ice surface Saturday.
Winds gusted up to 80 mph Friday, but conditions improved significantly Saturday afternoon.
He made 50 saves on Friday night in a 3-1 victory over the Calgary Flames, becoming only the third goaltender in NHL history to make that many stops in consecutive appearances since shots on goal became an official statistic in 1955-56.
Legendary netminder Gump Worsley accomplished the feat with the Rangers in 1963 and Al Rollins did it with the Chicago Black Hawks in 1955.
