Bucs looking at fullbacks, still test driving Cadillac

Posted by ESPN.com's Pat Yasinskas

Earnest Graham had a stellar performance Sunday as he switched over to fullback. But it doesn't sound like the Buccaneers have any plans to make his move from tailback permanent.

"You know what?" coach Jon Gruden said Monday. "Earnest is a heck of a tailback. We possibly could be looking for a fullback. Obviously moving a tight end into that position has always been a part of our contingency plan."

The Bucs are looking for a fullback with Byron Storer out for the season and B.J. Askew banged up. They'll likely sign a fullback in the next day or two. There could be some more movement in the Tampa Bay backfield.

Cadillac Williams is eligible to be activated from the physically unable to perform list. The Bucs have a three-week window in which they could activate Williams, who is recovering from a knee injury, and allow him to begin practicing. But it doesn't sound like the Bucs are ready to open that window just yet.

"We're going to keep looking at him," Gruden said. "We've said it time and time again: He's getting better and better and better. We're going to continue to work with him privately without activating him onto the 53-man roster immediately. But we really like what we've seen. It's been over a year now since he's had the injury. All of his hard work is going to pay off but it won't be this week that he's activated, but it could be coming soon."

There also is the possibility the Bucs could put Williams on the injured reserve list and delay his comeback until 2009.
