It sounds like Manson had two injuries at the end of last year?
He missed the end of the regular season after twisting his ankle and reaggravating his injury, and then missed the rest of the playoffs with what was reported as a "lower body injury" which seems like it led some outlets to specify his off season surgery was on his ankle. Turns out his surgery was on a torn oblique muscle he suffered in the playoffs.
It was reported last month he's still dealing with the "lower body injury" but knowing this team, they could just be calling the oblique injury a lower body injury, so who knows.
Hopefully the ankle won't bother him again this year, but it is concerning if he didn't have surgery on it, and he's still rehabbing it. Not clear if that's the case.
The good news though is Bednar thinks he'll be healthy enough to get one pre-season game in and presumably start the regular season.
