Detroit Red Wings forward Valtteri Filppula has a high-ankle sprain, general manager Ken Holland said.

Filppula will be in a cast for 2-3 weeks and will need 6-8 weeks to heal. He was injured early in the first period Wednesday, when he got slew-footed by Chicago's Andrew Shaw in Game 7 of the Western Conference semifinals.

Filppula might have played his final game as a Red Wing. He can become an unrestricted free agent on July 5 and there has been no recent contact talks between his agent and Holland.

“I made Fil and offer in August and September, we had some back and forth,'' Holland said. “I'm sure we'll have some conversation.''

Samuelsson might need surgery

Holland said forward Mikael Samuelsson might need surgery for an issue with his pectoral muscle that plagued him late in the season and in the playoffs.

Samuelsson missed the final 13 games of the regular season with the injury, which he sustained in a 7-1 loss to the Blackhawks on March 31. Samuelsson re-injured it in Game 7 against Anaheim in the first round and didn't play in the Chicago series.

“It hasn't healed, but he feels better every day,'' Holland said.

Combined with other injuries (pulled groin, broken finger), Samuelsson appeared in only four regular season games and five playoff games.
