The Bucs lost Williams, the 2005 NFL offensive rookie of the year, to a season-ending knee injury two weeks ago. Pittman started last Sunday against Indianapolis, but was carted off during the second quarter with a high ankle sprain that's expected to sideline him six-to-eight weeks.
The injuries leave the Bucs (3-2) without much experience at running back.
Earnest Graham, a contributor on special teams for most of his four years in the NFL, is set to make his first pro start Sunday against Tennessee. Rookie Kenneth Darby is the backup after beginning the season on the practice squad.
The Bucs brought in former Oakland Raiders fullback
Zack Crockett for a workout last week and took a look Tuesday at some other players whom Allen would not identify. The team also explored the possibility of a trade.
"
Right now we don't anticipate making a trade," Allen said, adding that unlike other sports, such deals are rarely made during the football season.
The general manager said an MRI revealed Pittman, the starting tailback during Tampa Bay's 2002 Super Bowl run, has a badly sprained ankle but that the Bucs remain hopeful that he will be able to play again this season.
"There's no fracture ... and Michael has been known to be a quick healer," Allen said.
