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.

The biggest concern for the Tampa Bay Buccaneers as they open training camp for their 50th season on Tuesday is the status of offensive tackle Tristan Wirfs and wide receiver Chris Godwin.
