Stamkos was hurt with 7:11 to play in the second period. He entered the day tied with Pittsburgh's Sidney Crosby as the NHL's leading scorer. Stamkos got tied up with Boston defenceman Dougie Hamilton and crashed into the right post.
His left skate appeared to hit the post first before his right leg crashed into it around the shin area. He tried to get up twice before going down to the ice in pain, grabbing his leg just above the ankle.
