The Bucs made a surprising move to bolster their offensive line by selecting Illinois left tackle Xavier Fulton.

The 6-foot-4, 302-pound Fulton could be an eventual replacement for Donald Penn, who will become an unrestricted free agent next season. Behind Fulton, Illinois led the Big Ten in offense and pass offense.

Fulton began his career as a right defensive end before tearing a knee ligament. He was granted a medical hardship in 2006 and returned the next season after making the transition to left tackle.

"It was a little difficult at first getting to adjust,'' Fulton said. "Especially, the biggest thing I had trouble with and so does everybody else learning pass blocking. It's totally different from the way you're taught to play defense. Defense is easy by comparison -- chase the ballcarrier. You can't be wrong if you chase the ballcarrier. Go tackle someone. Whereas on offense, you make one mistake and the entire play is busted and it's lost yardage.

"It was difficult at first but I think I got the hang of it over the past two seasons and I feel pretty comfortable at it now.''

Since the NFL combine, Fulton underwent surgery on his right shoulder.
