Bucs lose starting guard, may have to turn to rookie

Posted by ESPN.com's Pat Yasinskas.

Just days after getting rid of veteran tackle Luke Petitgout, the Bucs took another hit to their plans for the offensive line.

Starting guard Davin Joseph has undergone surgery for a broken foot and will be out for an extended period. That's a big blow to an offensive line the Bucs had been hoping would be dramatically improved this year.

Donald Penn, who is adequate at best, has taken over Petitgout's position. The loss of Joseph leaves the Bucs with a tough decision. Rookie Jeremy Zuttah worked in that spot with the first team today. Zuttah was expected to be the backup center and he had a very strong training camp.

The Bucs may decide to throw Zuttah in and let him sink or swim. The alternative is veteran Dan Buenning. But Buenning also can play center and the Bucs may want to keep him as an experienced backup for all three spots in the middle.
