The San Jose Sharks will name a captain before their season-opener against the Los Angeles Kings on Oct. 7, first-year coach Peter DeBoer said.

When that captain will be named is still unknown, although "it won't be the morning of the [Kings] game," DeBoer said. "I'll give [the media] a little more notice."

DeBoer has had a number of players serve as alternate captains during preseason games, among them forwards Joe Pavelski, Joe Thornton, Logan Couture and Patrick Marleau, and defenseman Marc-Edouard Vlasic. Marleau and Thornton previously have been Sharks captains.

"We've kind of spread it out amongst a group of guys that I think are all part of the leadership committee here," DeBoer said. "There wasn't a ton of thought put into it. The guys who have worn the 'A' in preseason are the guys who are, for me, a part of that leadership group that's here.

"I'm very happy with the leadership here. Real impressed with how they come to work every day, the professionalism, how serious they are. There's a lot of good things in that area here."

The Edmonton Oilers said that forward Jordan Eberle will miss four to six weeks with a shoulder injury.

Eberle left Tuesday night's game against Arizona in the first period following a collision against the wall behind the Coyotes' net.

Eberle was the Oilers' top scorer last season with 63 points (24 goals, 39 assists) in 81 games.

The Chicago Blackhawks and Brent Seabrook agreed to an eight-year contract extension on Saturday.

The deal is worth $55 million total, with a $6.875 million average salary that takes effect a year from now, sources told ESPN.com's Pierre LeBrun.

Seabrook was set to become an unrestricted free agent after the season. His last contract was for five years and $29 million. 

The Toronto Maple Leafs announced Sunday that the club has agreed to terms with free agent forward Brad Boyes on a one-year contract.

Boyes was originally invited to training camp with Toronto on a professional try-out.

Boyes, 33, appeared in 78 regular season games last season with the Florida Panthers, collecting 38 points (14 goals, 24 assists) and 20 penalty minutes. The Mississauga, Ontario native has registered 481 points (203 goals, 278 assists) in 762 career NHL games with the San Jose Sharks, Boston Bruins, St. Louis Blues, Buffalo Sabres, New York Islanders and Florida. 

Zdeno Chara suffered an upper-body injury during the first period of Thursday night's 4-3 shootout win against the New York Rangers at TD Garden and did not return.

The prosecutor overseeing the sexual assault investigation of Patrick Kane says the accuser's mother lied about finding an evidence bag in her doorway.

Erie County District Attorney Frank Sedita said during a news conference Friday that he is not sure how the two-day "dog and pony show" focusing on how evidence was handled affects the main case. Sedita said all the evidence, including the rape kit used to examine the accuser, was handled properly and is still in custody of authorities.

"Obviously there has been an effort to create a hoax," Sedita said. "I gotta figure out who was in on that, why they would do that and what it means vis-a-vis all the other evidence."

Questions about the bag were raised publicly Wednesday by the accuser's former attorney, Thomas Eoannou, who abruptly quit the case Thursday night and said he no longer believed the story about how the folded-up paper bag was found. Eoannou said he was still confident in the accuser's allegations against Kane.
