Rangers President and GM Glen Sather announced today that both Ryan Callahan and Carl Hagelin underwent surgery to repair a torn labrum in each of their left shoulders.

The procedures were performed by Dr. Andrew Feldman earlier today at the NYU Langone Medical Center's Hospital for Joint Diseases in Manhattan.

Kings center Jarret Stoll practiced Thursday without a no-contact jersey for the first time in more than two weeks, but his status for Game 1 of the Western Conference finals against the Blackhawks on Saturday remains uncertain.

Stoll was hit in the head by Sharks left winger Raffi Torres in Game 1 of the Western Conference semifinals on May 14 and hasn't played since. 

Cleared to play without a plastic apparatus protecting his lower face for the first time since returning from a broken jaw, Sidney Crosby said he'll need a few days to adjust.

Crosby wore a traditional helmet with no mouth or jaw protection during the Penguins' practice Sunday, according to an ESPN.com report. 

Veteran center Brad Richards will be a healthy scratch Thursday night as the Rangers face elimination against the Bruins in Game 4 of the Eastern Conference semifinals, according to an ESPN.com report.

Richards told reporters that coach John Tortorella called him to tell him the news Thursday morning.

"I don't know if 'surprised' is the right word, just disappointed," Richards said with an air of dejection.

Rangers goaltender Henrik Lundqvist suffered a left shoulder injury late in Game 2 on Sunday, but he plans on battling through it.

Lundqvist hurt his shoulder with 4:52 remaining in the third period after making a save on Bruins winger Daniel Paille.

Game 3 is Tuesday at Madison Square Garden.

"Yeah, it's under control," Lundqvist said after practice Monday, according to an ESPN.com report. 

Blackhawks forward Viktor Stalberg likely will play in Game 3 of the semifinal series against the Red Wings after being a healthy scratch in the first two games, coach Joel Quenneville said Sunday.

The Hurricanes say they expect Eric Staal to be ready to start next season after suffering a scary-looking knee injury during an international tournament.

The team said Staal underwent an MRI on his right knee Saturday and it revealed a third-degree sprain of his medial collateral ligament.

Wild goalie Niklas Backstrom has undergone sports hernia surgery, according to an ESPN.com report.

The team announced that Backstrom's operation went as planned on Thursday morning in Philadelphia. 

Alex Ovechkin played the last two games of the Capitals' season with what the team said Thursday is a hairline fracture in his left foot.

Ovechkin was hurt during Game 6 of Washington's first-round playoff series against the Rangers, according to an ESPN.com report.

Ducks defenseman Toni Lydman's status for the remainder of the first-round series against Detroit is very much in doubt as he recovers from a hit that earned Red Wings forward Justin Abelkader a two-game suspension.

Lydman is still dealing with headaches as a result of the Game 3 hit and won't play in Game 4 on Monday night.
