Zubov placed on IR retroactive to Jan. 17 with groin injury
Zubov, 37, has missed seven games with a groin injury. In a statement issued Thursday, the Stars said Stephan would back up goaltender Mike Smith Thursday night in Minnesota.
The Stars said they will leave starting goalie Marty Turco in Dallas as a precaution with a sore neck.
Stephan, 24, made his NHL debut Oct. 13 at Chicago and blocked 38 of 40 shots in a 2-1 overtime loss. In 39 American Hockey League games, he's 17-16-2 with a 2.60 goals-against average, a .907 save percentage and two shutouts.
