Malkin appeared to hurt his shoulder in the final minutes of regulation in a 5-4 overtime victory against Toronto on Saturday night when he collided with Maple Leafs forward James van Riemsdyk. Malkin returned to play one more shift but did not take the ice in overtime.
Coach Dan Bylsma says Malkin will be re-evaluated late Sunday night, but added the injury was not related to the concussion Malkin sustained last month that forced him to miss four games.
Malkin has five goals and 19 assists in 21 games this season for Pittsburgh.
There's not much to say. We played like [garbage]. I think every guy in the room should be completely embarrassed about how they played tonight. Every single person. To start a road trip, one of the biggest road trips and have a division rival chasing you down and have a ton on the line, it's ridiculous how we played tonight.
