Coach Jon Gruden said after this afternoon's practice that he remains concerned about RB Warrick Dunn's back and even wondered aloud whether Dunn should have played against the Cowboys on Sunday.

"We probably shouldn't have allowed him to play," Gruden said of Dunn, who has a pinched nerve in his upper back. "We choose not to use him much. But he is such a warrior. He has played this game for so long. But, I agree. He wasn't himself on Sunday in Dallas. That's a big part of our offense."

With Dunn touching the ball just three times, the decision to dress him and leave Michael Bennett inactive backfired. Gruden wasn't able to call running plays on which he prefers to use Dunn over Earnest Graham. Plus, Dunn is an accomplished receiver who adds another dimension to the offense.

It's too early to say, but it's possible the Bucs will consider sitting Dunn this week at Kansas City to allow the injury some time. As of Sunday, Dunn was in pretty bad shape and it's conceivable he hasn't improved much since.
