Blackhawks’ Corey Crawford participates in drills

The goaltender suffered his second known concussion in less than a year in December.

Corey Crawford participated in drills Saturday morning at MB Ice Arena with the Blackhawks for the first time since suffering his second known concussion in less than a year. He left the ice prior to the Blackhawks practicing.

Crawford worked 1-on-1 on his lateral movement with goaltending coach Jimmy Waite before taking shots.

Crawford then had teammates David Kampf, Dominik Kahun and John Hayden take shots against him. All the shots appeared to be low and into his pads.

Blackhawks head coach Jeremy Colliton cautioned reading into Crawford’s return to the ice too much.

Crawford was diagnosed with a concussion after his head hit the goalpost during a collision in the first period against San Jose on Dec. 16. He left the game after the collision and did not return. The next day he was placed on injured reserve.

Colliton has said he expects Crawford to play once he returns, and on Jan. 6, general manager Stan Bowman said “if he’s medically cleared to play, then he’ll play again.”
