Anyone know any details? This is the first I've heard about it.
Also, prospect Anthony Mantha, who is expected to get a legitimate shot to make the big club’s opening-night roster, suffered a knee injury Monday in the NHL Prospects Tournament at Centre ICE Arena. He did not play in Tuesday’s final prospect game and his availability Friday – when the Wings begin on-ice workouts – is uncertain.
It may just be precautionary, someone on reddit mentioned this:
He limped off the ice in the prospect game yesterday, then returned a few minutes later and came back and scored a goal. I'm sure it's all precautionary.
