Tristan Wirfs should be anchoring the Bucs offensive line, bracing against edge rushers and keeping the pocket clean for Baker Mayfield. Instead, the All-Pro tackle hobbled across the practice field Thursday morning with a single crutch under his left arm and a heavy brace on his surgically-repaired right knee.

Tampa Bay Buccaneers left tackle Tristan Wirfs underwent surgery earlier this month that could knock him out to start the season. Coach Todd Bowles, however, offered a more optimistic timeline for the star's return.
