The hit came at 18:22 of the second period in Colorado's 3-2 over the Coyotes on Thursday night. Torres lowered his shoulder and appeared to hit Hejda on the side of the head.
Hejda lay on the ice for about a minute before being helped to the locker-room.
Torres was not penalized on the play, and infuriated Avalanche coach Joe Sacco screamed at the officials.
