TAMPA — RB Cadillac Williams apparently has hit another bump on the comeback trail.
He has a hamstring strain and is listed as questionable for Sunday's game at Detroit.
Williams, who was activated to the 53-man roster from the physically unable to perform list last week, hoped to get some playing time after Earnest Graham was placed on injured reserve Wednesday with a high ankle sprain.
In fact, coach Jon Gruden made no mention of Williams' injury at his Friday news conference. Williams had full participation in practice Friday.
But when the injury report was released at 4 p.m., Williams was listed as questionable along with TE Alex Smith (ankle) and S Jermaine Phillips (broken left forearm).
"Carnell has done some good things and I think he'd be ready to play," Gruden said. "There's a chance."
But Gruden warned special teams concerns might prevent Williams from being active Sunday.
"I think we'll meet later today and check out the injury status of everybody and the progress that we feel like the guys have made," Gruden said.
"So there's more to it than just, 'Let's make a hasty decision here.' We'll let you know. There's a chance we can get Carnell up."
BIG HIT, BIG FINE: Vikings DE Ray Edwards was fined $25,000 by the NFL for two infractions Sunday, including a late hit on Jeff Garcia that opened a gash on the Buc QB's chin.
The NFL said that Edwards committed another foul that was deemed unnecessary roughness when he "leg whipped" an unidentified Bucs player.
The $25,000 sum is a sizable fine, which Edwards is permitted to appeal. Based on his 2008 base salary of $445,000, the third-year player out of Purdue makes roughly $27,812 each game.
Earlier this week, Vikings DE Jared Allen was fined $25,000 for a spate of late hits, most notably on Packers QB Aaron Rodgers in their Nov. 9 game.
