Connor McDavid has undergone successful surgery to repair his fractured clavicle, the team announced Wednesday evening.

McDavid suffered the injury Tuesday night when he went crashing into the boards along with two Philadelphia Flyers defencemen.

Oilers general manager Peter Chiarelli revealed the rookie is expected to miss “months” as he recovers from the injury.

McDavid has five goals and seven assists on the season, and was named rookie of the month for October.
