Clifton Smith promoted to active roster

RB Clifton Smith has been promoted to the active roster, likely to help in the return game and supplement the depth at running back if Warrick Dunn (back) is unable to play Sunday.

Smith probably will take the place of rookie Dexter Jackson, who has been returning punts and kicks to this point. He has been under much scrutiny after his struggles in recent weeks. The Bucs play at Dallas on Sunday.

It's unclear at this point who will be released from the active roster to make room for Smith. The Bucs have not yet officially announced the transaction.
