Krejci was injured in a collision with Ottawa Senators forward Bobby Ryan near the end of the second period of the Senators' 3-1 home win on Sunday. Krejci did not play in the third period. Shortly after his teammates left the ice here Monday, Krejci left the arena with his right arm in a sling.
He was placed on injured reserve, so he will not be available to the Bruins when they host the Montreal Canadiens in the 2016 Bridgestone NHL Winter Classic at Gillette Stadium in Foxboro on Friday (1 p.m. ET, NBC, CBC, TVA Sports).
