Blackhawks place G Crawford on injured reserve
Crawford got hurt in the first period of Sunday's 7-3 loss to San Jose when the back of his head struck the right post during a goalmouth pileup. He also missed the final part of last year and the start of this season because of a concussion.
Crawford, who turns 34 on Dec. 31, is 6-14-2 this season with a 3.28 goals-against average and a .902 save percentage.
Also Monday, the last-place Blackhawks recalled goaltender Collin Delia on an emergency basis from Rockford of the American Hockey League. He made his NHL debut in March and went 1-1 in two starts with Chicago.
The Blackhawks host Nashville on Tuesday night.
