Flyers forward Joel Farabee will be out for the next three-to-four months following a successful disc replacement surgery, the team announced earlier today.
Joel Farabee Injury, Surgery Update
I’m not going to pretend I know everything about the Flyers but there seems to be a consensus online that fans really didn’t know much about the injury to Farabee in the first place. Sure, he was hurt a few different times throughout the season but I definitely don’t see anything to this extent. I’m looking through old posts from the media and I don’t see it listed anywhere.
Is there a chance I’m missing something? Maybe, but as we all know, the Flyers are a poorly run hockey organization so I wouldn’t be surprised if they just dropped this surgery news on fans today.
Question: It was clear to everyone how bad the Flyers were last season. They were basically dead in the water midway through the year. Why would they wait so long before Farabee actually had surgery?
That part doesn’t make sense to me.
Now, it looks like this injury will almost certainly prevent Farabee from being ready for the start of next season. He played in 63 games of the Flyers last season, scoring 17 goals and 17 assists.
Farabee signed a six-year $30 million extension last September.
