OTTAWA -- The Red Wings were already without their best defensive defenseman in Ottawa.
Then they lost arguably their best defensive forward in the second period.
The team announced in the second period that center Luke Glendening had suffered an upper-body injury and would not return to the game.
"Luke's going to be out for a little bit," Wings coach Jeff Blashill said after the game. "I don't know how long. I'll know more on Friday. But he'll definitely miss some time."
Glendening finished with 10 shifts for 6:39, had one shot, one hit, one blocked shot and was 5-of-6 in face-offs.
"He's a warrior out there," Justin Abdelkader said. "Shot-blocking machine. Unfortunate to see him go down and not come back. Heart and soul type of guy. The guys in the lineup have to fill the void. Each of us can step up."
The Wings do have a defensive forward in Christoffer Ehn, who was a healthy scratch for the Senators game.
