PHOENIX (CBS) – The Blackhawks beat the Phoenix Coyotes Sunday night and moved into a fifth place tie in the NHL Western Conference, but lost Patrick Sharp to an injury.

Sharp had to leave the game with 1:35 left in the first period. The Chicago Sun-Times reported that Sharp was “favoring his left knee” as he left the ice, following a collision with the Coyotes’ Rostislav Klesla.

Sharp did not return for the rest of the game. The Blackhawks would not elaborate about how seriously he was injured, or how long he might be out, the Sun-Times reported.

The Blackhawks went on to win when Chris Campoli scored a power-play with 6:34 remaining in the game.

Campoli, acquired from Ottawa on Feb. 28, scored his first goal for the ’Hawks when he took a cross-crease pass from Jonathan Toews and put a shot into the vacated left side of the net before Ilya Bryzgalov, covering the right side, could recover.

Duncan Keith also scored for the ’Hawks.

Eric Belanger scored for the Coyotes, whose five-game winning streak was snapped. Phoenix, fourth in the West with 89 points, hadn’t lost in regulation since March 3 (6-0-1).

Keith gave the Blackhawks a 1-0 lead on a power-play goal with 30 seconds left in the first period. He fired the puck between Bryzgalov’s pads from the center of the left circle.

Belanger tied it at 18:43 of the second when his blast from the top of the right circle bounced off Nick Leddy’s skate and past partially screened goalie Corey Crawford.
