Comeau, who has not played since sustaining an upper-body injury Dec. 22 against the Florida Panthers, was on a line to the left of center Evgeni Malkin and right wing Patric Hornqvist during the morning skate Wednesday. He is sixth on Pittsburgh with 11 goals in 32 games, six more goals than he scored with the Columbus Blue Jackets last season.
Penguins coach Mike Johnston did not confirm if Comeau will return against Detroit.
"It feels good," Comeau said. "I had a good, hard skate Monday with the team. I skated yesterday. Third one today and it reacted really well, so hopefully I can get in there tonight. … I've been skating without a puck for probably two-and-a-half weeks now and I've been skating with a puck for 10 days. So it was nice to get on the ice on Monday.
"I feel good, feel confident."
