Joni Pitkanen's broken left heel bone, an injury suffered Tuesday night against the Washington Capitals, has ended the Canes defenseman's season.

General manager Jim Rutherford said Wednesday that Pitkanen has a broken calcaneus bone and would sidelined 10 to 12 weeks.

Pitkanen was injured late in the second period at PNC Arena as he attempted to touch up the puck and force an icing call against the Caps. He went sliding into the boards, pinning his leg under him, and needed to be carried off the ice on a stretcher.

Canes coach Kirk Muller said after the game Pitkanen injured his ankle or heel.

Pitkanen's injury leaves the Canes with seven healthy defensemen: Tim Gleason, Joe Corvo, Jay Harrison, Bobby Sanguinetti, Jamie McBain, Brett Bellemore and Marc-Andre Bergeron, who was obtained Tuesday in a trade with Tampa Bay.
