The Buccaneers have released offensive OT Luke Petitgout who was suspended for 4 games by the NFL for violating league policy shortly after the Bucs cut him.  25-year old Donald Penn will be the likely starter at left tackle for the Bucs this season.  He played in 16 games (12 starts) for the Bucs in 2007.  QBs should keep their head on a swivel with Penn watching there backs.
