Wirfs was diagnosed with an MCL sprain following Sunday's game versus the 49ers, Ian Rapoport of NFL Network reports.
It's a positive development for Wirfs, who may have had to miss the rest of the season if he'd instead torn his MCL in Week 10. He's not expected to miss more than a couple of games as he recovers, during which time Justin Skule would figure to step into a starting role on the Buccaneers' offensive line.
