The Penguins have been forced to play without Sidney Crosby for much of the past two seasons after he experienced complications with concussion, and now hope their anguish will not be extended to Malkin, reigning holder of the Hart Trophy as the NHL's most valuable player.
Malkin was injured against Florida on Friday when he collided with defenseman Erik Gudbranson and was forced off the ice. He was diagnosed with a concussion on Sunday.
"Evgeni suffered some short-term memory loss and therefore was diagnosed with a concussion," Penguins coach Dan Bylsma told the team's website. "He's had no other symptoms."
Malkin has four goals and 21 points this season for Pittsburgh (13-6-0), who lie second in the Eastern Conference.
