PITTSBURGH — Pittsburgh Penguins rookie center Evgeni Malkin took part in limited contact drills in practice with his teammates, and head coach Michel Therrien said Friday the Russian star could make his NHL debut as early as this week.

Malkin dislocated his shoulder in a preseason game Sept. 20. He probably won't play Saturday against Carolina, and doctors will decide whether he will play Wednesday against New Jersey, Therrien said.
