The Washington Capitals stunned the hockey world with their Game 1 and 2 victories over the Tampa Bay Lightning in South Florida, and they did it despite star centerman Nicklas Backstrom being sidelined with an upper-body injury.

However, Caps head coach Barry Trotz told the media on Monday that Backstrom is "day to day" and the decision to return to the lineup is completely up to him, according to Isabelle Khurshudyan of The Washington Post.

Backstrom left Game 5 of Washington's second-round series against the Pittsburgh Penguins in the third period and has not seen any game action since.

Prior to getting hurt, Backstrom was in the midst of a sensational postseason, racking up three goals and 10 assists through 11 games.

In a historic decision Monday morning, the U.S. Supreme Court voted 7-2 in favor of overturning the federal ban on state-sanctioned sports betting, paving the way for legalized wagering across the country.

The official decision contends, "Congress can regulate sports gambling directly, but if it elects not to do so, each State is free to act on its own."

The case was contested in New Jersey, which is now eligible to make the change immediately under the ruling. According to gaming and sports attorney Daniel Wallach, it's expected Monmouth Park Racetrack will be one of the first to offer sports betting in as little as two weeks' time.

The Professional and Amateur Sports Protection Act came into law in 1992, and while it didn't officially ban sports betting nationwide, it ruled states were not allowed to regulate and tax sports betting.

Nevada was the lone exception to the rule, creating a sports betting haven in the desert, most notably in Las Vegas.

According to Pete Williams of NBC Sports, the American Gaming Association estimates the men's NCAA basketball tournament alone brings in $10 billion per year, with only three percent wagered legally in Nevada.

New Jersey may be the state to benefit immediately from the decision, but it certainly won't be the only one. Mississippi, Pennsylvania, and West Virginia recently passed laws that would allow sports wagering contingent upon Monday's decision.

Wallach also reports 15 other states, including New York, have introduced legislation that would regulate sports betting related to the Supreme Court's ruling. With the ruling now complete, many expect those states to move forward with legislation to allow betting later this summer.

The move to legalize sports betting has picked up a great deal of traction in recent months, with MLB, the NBA, and the PGA Tour leading efforts to ensure safeguards are in place to protect the integrity of their sports. The NBA and MLB are also seeking to be paid a percentage of all legal wagering on their events. NBA vice president Dan Spillane in January told the New York state legislature leagues want a 1 percent cut for "integrity" services, ESPN's Brian Windhorst reports.

The official decision contends, "Congress can regulate sports gambling directly, but if it elects not to do so, each State is free to act on its own." That opens the door for each state to individually decide whether to allow sports betting in its region.

The case was contested in New Jersey, a state that will likely be the first to make the change under the ruling.

The Professional and Amateur Sports Protection Act came into law in 1992, and while it didn't officially ban sports betting nationwide, it ruled states were not allowed to permit sports betting.

Nevada was the lone exception to the rule, creating a sports betting haven in the desert, most notably in Las Vegas.

According to Pete Williams of NBC Sports, the American Gaming Association estimates the men's NCAA basketball tournament alone brings in $10 billion per year, with only three percent being wagered legally in Nevada.

A number of states have introduced legislation in the past few months that would legalize sports betting once the Supreme Court ruled, so expect those areas to act fast following Monday's decision.

TAMPA, Fla. (AP) The Washington Capitals scored in the opening minute of the game and twice in the last 1:02 of the second period to pull away to a 6-2 victory over the Tampa Bay Lightning on Sunday night and a 2-0 lead in the Eastern Conference final.

Evgeny Kuznetsov and Lars Eller each had a goal and two assists. Alex Ovechkin and Tom Wilson had a goal and an assist apiece.

Devante Smith-Pelly and Brett Connolly also scored for the Caps, who took the first two games of the best-of-seven matchup on the road. Since 1974-75, teams that take a 2-0 lead in the conference final or semifinal have a series record of 39-2 (95.1 percent).

Game 3 is Tuesday night in Washington.

Brayden Point and Steven Stamkos had early power-play goals for Tampa Bay, which rebounded after falling behind on Wilson's goal 28 seconds into the game.

John Carlson is going to become a very rich man this offseason.

A pending unrestricted free agent, Carlson recorded an assist on Devante Smith-Pelly's second-period goal, setting a Capitals record for points by a defenseman in a single postseason.

Carlson led all NHL blue-liners in points during the regular season with 68 and has produced at an even greater rate during the playoffs.

Hands down the best defenseman set to hit the open market this offseason, Carlson is playing the finest hockey of his life at an opportune time.

Washington Capitals forward T.J. Oshie was issued a two-minute high-sticking minor in the first period of Game 2 against the Tampa Bay Lightning, even though his stick never touched Victor Hedman's face.

It's clear on the replay that Oshie's stick tipped the fluttering puck as Hedman went to catch it. When the puck changed direction off Oshie's blade, it hit Hedman in the face, which is why he went down.

On the ensuing power play, Steven Stamkos blasted home a one-timer that gave the Bolts a 2-1 lead Sunday night.

It may have been a tough call for the referee to make in the heat of the moment, but the Capitals likely don't feel much sympathy.

The undefeated Swedes will have to play the rest of the tournament without a key offensive figure.

Vancouver Canucks prospect Elias Pettersson will miss the remainder of the World Championship after suffering a thumb injury Sunday against Switzerland, according to Uffe Brodin of Hockeysverige.

After setting the SHL (Sweden's top professional league) record for points by a U20 player in both the regular season and the playoffs, Pettersson finished with a goal and three assists in six games at the worlds.

Sweden should be well-equipped to handle the loss, though, as it recently added Nashville Predators forwards Filip Forsberg and Viktor Arvidsson to an already impressive crop of players up front.

Canucks fans will likely have to wait until training camp to get their next look at Pettersson.
