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.
For six months, it's a really good accomplishment. But as soon as April [11, the end of the regular season] comes around, no one thinks about the regular season anymore. For six months, it's a real battle to get into the playoffs in the NHL these days. There are a lot of good teams, and it takes consistency over a long time.
