Not confirmed, but it looks like Mattias will be out for a while and won't be back soon, said Edmonton's coach Kris Knoblauch ahead of tonight's NHL game against Los Angeles.
He's not playing tonight and won't play in the first round of the playoffs, continued Knoblauch, according to nhl.com.
The Swedish defenseman had missed seven games but returned for the game against San Jose on Saturday night. However, he left the ice after just two shifts and was then not included in the game against Winnipeg on Monday night.
Ekhholm has scored 33 points in 65 games this season, including nine goals.
Edmonton is clear for the Stanley Cup, which begins this weekend.
