Star forward Peter Forsberg injured his wrist while playing with the Swedish Elite League club MoDo on Thursday.
Forsberg, who usually skates with the NHL's Colorado Avalanche, left a Swedish game against Linkoping in the third period after colliding with Johan Franzen.
X-rays showed a possible bone fracture in the wrist and Forsberg underwent surgery at the hospital, according to the Swedish paper Aftonbladet,.
"In the best-case scenario, he'll be on the injured list for eight weeks," MoDo doctor Kim Thorsen told the paper. "But if it really is a fracture, the whole season is probably lost."
Kent Forsberg, Peter Forsberg's father and MoDo's coach, sounded more hopeful.
"I spoke with Peter on Friday morning," Kent Forsberg told the Swedish newspaper, Aftonbladet. "He was optimistic about playing again this season and if he is in good spirits then I am too."
The injury marred the festive atmosphere of a game in which Vancouver Canucks captain Markus Naslund returned to MoDo to play during the current NHL lockout.
Naslund received a standing ovation from the crowd but didn't score in his first game back in his native Sweden.
"It was wonderful to be back and play, but [Forsberg's injury] dampens it a bit," Naslund said.
The Canucks star grew up with Forsberg in the small Swedish town of Ornskoldsvik and have skated together many times in international play.
Thirteen current and former NHL players are currently with MoDo during the NHL lockout.
