McCarthy (knee) is expected to undergo knee surgery to address a meniscus issue after having an MRI on Monday, Adam Schefter of ESPN reports.
McCarthy reported knee soreness over the weekend, and the MRI he underwent Monday revealed an issue serious enough to require surgery. Ian Rapoport of NFL Network reports that McCarthy will require either a meniscus trim, which would carry a recovery timeline of at least a few weeks, or a repair which could sideline the rookie quarterback multiple months. Even if McCarthy is able to make a rapid return, Sam Darnold now has a clear path to the Week 1 starting gig for Minnesota.
