from Dana Wakiji of the Wings website,
Wings coach Jeff Blashill expects Glendening and Mantha to play in Buffalo Thursday.
"I anticipate both of them to be maintenance days," Blashill said. "They both got little issues. I think they're both going to be ready to play tomorrow. I won't know that 100 percent until tomorrow. Glendening, certainly I expect to play. He's had a number of nagging injuries that he plays through. We just felt it was best for him to have a rest. Mantha blocked a shot the other day. He's got some swelling, so he'll hopefully be able to feel fine in the skate tomorrow and be able to play.
