Colorado Avalanche star Nathan MacKinnon left the ice after being bloodied on a hit in the first period of Wednesday night's game against the Boston Bruins and did not return.

The Avs said MacKinnon suffered an upper-body injury after he absorbed an open-ice shoulder shot from the Bruins' Taylor Hall. The hit caused MacKinnon's own stick to snap back into his face. Blood gushed from his nose to the ice as MacKinnon lay face down.

MacKinnon, a five-time All-Star, was able to skate off on his own but didn't return. Hall was originally given a five-minute major that was reduced to two minutes after a video review.

The Avs rallied to a 4-3 win in overtime for their 17th straight home victory.
