Edmonton Oilers defenseman Andrej Sekera tore his ACL and will be out 6-9 months, Oilers GM Peter Chiarelli announced on Tuesday.
Sekera was injured in Game 5 of the Oilers second-round series against the Anaheim Ducks on May 5.
The 30-year-old Sekera finished second among Oilers blueliners in scoring (35 points) and average time on ice (21:29 per game).
Chiarelli said he believes Sekera is scheduled for surgery Thursday.
"He's our No. 1," Oilers coach Todd McLellan told the Edmonton Journal. "He's playing his game in our system and when players do that they don't over-extend themselves. He's healthy and a year in and he understands what the organization is about. He has more experience with our team, not just experience in the league. He knows language and situations better. He's playing to his strengths in our structure."
