he Tampa Bay Buccaneers aren’t ready to write Cadillac Williams off for the entire 2008 season.

The Bucs placed the running back on the physically unable to perform list on Tuesday afternoon, meaning Williams won’t be available for the first six games. After that, a three-week window opens during which Williams can begin practicing and the Bucs will have to decide whether to activate him or put him on the injured reserve list for the remainder of the season.
