Bucs release Petitgout

Posted by ESPN.com's Pat Yasinskas

The Bucs just made a surprise move, releasing left tackle Luke Petitgout.

He was attempting to come back from ACL surgery and progress had been slow. The Bucs initially hoped Petitgout would be ready for the start of training camp. But coach Jon Gruden admitted last week that the outlook wasn't bright. They released Petitgout with the designation of failed physical and filled his roster spot by signing fullback J.D. Runnels, who was drafted by the Bears in 2006.

The move leaves Tampa Bay thin at left tackle. Donald Penn, who filled in after Petitgout was hurt last year, has spent training camp working with the first team. Penn is far from dominant, but the Bucs don't have any real alternatives on the current roster. The Bucs were hoping Anthony Davis could step up in camp, but he didn't stand out.

The Bucs likely will bring in another tackle when other teams start making roster cuts, but it will be difficult to find a starting-caliber left tackle. They likely will have to stick with Penn and hope for the best.
