Ottawa Senators goaltender Robin Lehner and forward Clarke MacArthur have been diagnosed with concussions, general manager Bryan Murray told the Senators website Friday.

Lehner and MacArthur were injured during a game Monday against the Carolina Hurricanes when they collided as MacArthur skated back to defend an odd-man rush by the Hurricanes.

Also, Murray said forward Chris Neil had surgery to repair his broken left thumb. The Ottawa Sun reported a plate was implanted and Neil will be out four to five weeks.
