There's much for the Capitals to evaluate after a tough loss late in the season and an injury that could cloud their entire playoff outlook.

Alex Ovechkin was injured early in the third period of a 4-3 shootout loss to the  Maple Leafs on Sunday night, crashing into the boards and getting ruled out with an upper-body injury. 

Ovechkin's uncertain status is the most alarming situation facing the Capitals with the playoffs beginning in just over a week.

Vegas Golden Knights goalie Robin Lehner is undergoing season-ending surgery for a lower-body injury, sources told ESPN on Friday.

Lehner suffered the injury in a March 8 loss to the Flyers in Philadelphia. He left the team's road trip to receive more testing after the initial injury and missed Vegas' next several games.

Auston Matthews remains out for the Maple Leafs when they play the Flyers at Scotiabank Arena on Tuesday.

The forward is day to day with a "minor injury." He missed a 4-2 win against the Islanders in Toronto on Sunday.

"We're not just resting Auston in this case," Maple Leafs coach Sheldon Keefe said. "He's got an injury that maybe he could play through but that doesn't make sense to do so. It just speaks to the fact that we are looking bigger picture here. We've got individual accomplishments, team accomplishments in the regular season. We're mindful of them and they're important in their own way, but the ultimate goal is for us to be ready to compete come playoff time. That's what it's all about."

Vancouver captain Bo Horvat is expected to be out at least two weeks after taking a shot off his right ankle in the Canucks' 7-1 home victory over Arizona on Thursday night.

Fighting for a playoff spot, the Canucks said Friday the center will be re-evaluated in two weeks, a timeline that means he may have played his last game of the regular season. 

While the Kings battle for a playoff position in the Western Conference, veteran defenseman Drew Doughty will miss the rest of the season after undergoing surgery on his wrist.

The former Norris Trophy winner had surgery Monday, the team said. He is expected to be ready for training camp, but his absence damages the Kings' hopes of ending their three-year playoff drought.

New Jersey Devils star Jack Hughes will miss the rest of the 2021-22 NHL season because of a knee injury, the team announced Tuesday.

Hughes, 20, suffered an injury to his left knee during the Devils' loss to the New York Islanders on Sunday, on a hit by forward Oliver Wahlstrom.
