Blackhawks leading scorer Patrick Kane has left the game against St. Louis after a second-period collision with Brenden Morrow.

Kane was favoring his left leg, but went to the dressing room under his own power Wednesday night. He was injured at 7:56 of the second period and didn't return for the third.

Morrow fell into Kane after he was checked by Chicago's Sheldon Brookbank deep in the Blues zone.

Kane has 29 goals and 39 assists in 68 games.
