Jerick (Jet) McKinnon makes his case on Twitter. Raheem Mostert says “hummmm.”

Here is some bad news for the Raheem Mostert contract re-negotiating team. Check out the workout Jerick (Jet) McKinnon posted on Twitter. McKinnon, of course, has been battling knee problems since he tore his ACL before the 2018 season.

He’s tried several procedures and the team was hopeful he’d be back for 2019, but ended up having another knee surgery in August and was out for the year. It would not have been a huge surprise to find he was unable to answer the bell if this season happens. He wouldn’t be the first to have a chronic knee injury derail his career.
