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.

Pavel Datsyuk says he hopes to sign a new deal with the Red Wings this summer, according to an ESP.,com report.

Red Wings GM Ken Holland wants to sign Datsyuk to another deal as early as July 5.

Stephen Walkom is one of eight referees that will officiate the conference finals set to begin this weekend between the Blackhawks and Kings, as well as the Penguins and Bruins, according to an ESPN.com report.

Walkom called controversial coincidental roughing penalties late in the third period of Chicago's Game 7 overtime victory on Wednesday night. 

The Blackhawks and Red Wings deemed the United Center's ice satisfactory Wednesday prior to Game 7 of their Western Conference semifinal series, despite a Rolling Stones concert the night before and high heat and humidity, according to an ESPN.com report.

"It's fine," Blackhawks coach Joel Quenneville said of the ice after Wednesday's morning skate.

Rangers President and GM Glen Sather announced today that head coach John Tortorella has been relieved of his coaching duties.

Under Tortorella, the Rangers posted their second most wins all-time in a single season with 51, and tied for second in franchise history with 109 points in 2011-12.  He became the 30th coach in NHL history to coach 800 games on March 27, 2012, at Minnesota (3-2 win), and won his 100th game as Rangers Head Coach with a 5-3 win on November 5, 2011, vs. Montreal.  On March 26, 2013, Tortorella became the 30th head coach in league history to register his 400th NHL coaching victory, with a 5-2 win at Philadelphia. He also passed Tom Renney for fourth on the Rangers' all-time wins list with a victory on April 10, 2013 vs. Toronto.

Tortorella was named the 34th head coach in franchise history on February 23, 2009. 

After a dreadful postseason that has stirred talk that the Rangers will release him, veteran Brad Richards says he is still hoping to return to the team next season.

"I signed here to be a Ranger a lot longer than a year and a half," he said. "I still hope to do that, but I gotta take care of how I can play and that's all on me."

Rangers defenseman Marc Staal said he does not expect his injured right eye to ever make a full recovery, but he does expect to resume playing at the highest level possible, according to an ESPN.com report.

Staal sustained a small tear in his right eye after taking a puck to the face in a game against the Flyers March 5. He missed 27 regular-season games and 11 playoff games as a result. 

"It's probably not going to be 100 percent," Staal said of his injury, "but that's not to say it's not going to get a lot better. It's still improving."

The NHL has approved the sale of the Coyotes to a group of Canadian-led investors, but the deal is contingent on reaching an agreement with the city of Glendale, according to an ESPN.com report on Saturday.

The NHL agreed to sell the team to Renaissance Sports & Entertainment, a group headed by George Gosbee, Anthony LeBlanc and Daryl Jones, according to the people, who spoke on condition of anonymity because there had been no official announcement.

They said commissioner Gary Bettman, deputy commissioner Bill Daly and the prospective buyers will meet with Glendale officials on Tuesday.

Veteran defenseman Andy Sutton has retired, ending a 15-year NHL career beset by injuries, according to an ESPN.com report on Wednesday.

Sutton played in 676 NHL games, most recently with Edmonton in 2011-12. 

The Canucks fired coach Alain Vigneault on Wednesday, according to an ESPN.com report.

The team also fired assistants Rick Bowness and Newell Brown.

Vigneault, the Canucks' all-time leader in coaching wins, led the club to six Northwest Division titles, two Presidents' Trophy titles and an appearance in the 2011 Stanley Cup final.
