Source: Buccaneers' Tristan Wirfs believed to have sprained MCL

TAMPA, Fla. - The Buccaneers believe that All-Pro left tackle Tristan Wirfs suffered a sprained MCL in the first half Sunday against the 49ers , a source told ESPN's Jeremy Fowler.

The three-time Pro Bowl selection and team captain will require additional testing, including an MRI, to determine the severity, the source told Fowler.

Wirfs suffered the injury on a third-and-7 play with 5:06 to go in the second quarter. He was lining up against Nick Bosa while pass blocking when the injury occurred.

He was replaced by former 49ers offensive tackle Justin Skule , who played for San Francisco from 2019 to 2021. Skule started four games this season at right tackle when Luke Goedeke was sidelined with a concussion.
