It sounds like Morgan Frost will have to wait a while before he steps back onto the ice. Flyers GM Chuck Fletcher announced today that Frost is getting surgery to repair his shoulder, and he will likely be out for the remainder of the 2021 season.
Frost initially got hurt in the third game of the season. He was in the lineup to replace an injured Sean Couturier (who also hasn't returned to the ice yet).
For now it appears that Connor Bunnaman will continue to take Frost's spot on the roster, and Bunnaman will stay in the lineup until Sean Couturier is healthy enough to return.
