At 33, Dunn's best days are far behind him, but he still can pick up a few yards and is a decent receiver. He has not had more than five touchdowns in a season since 2004 so do not expect many touchdowns; just make sure he is not still a free agent in your league.

If you have to play Dunn, this week is the week to do it. He and Tampa Bay face the Lions' 32nd-ranked run defense.

Carnell Williams should play against Detroit for the first time even though he likely will not be ready for a heavy load immediately. Rookie Clifton Smith has to stop fumbling if he wants to keep playing.

Other potential free agents to consider:

*J.J. Arrington, RB, Cardinals: In two games since bursting out as a must-start, Tim Hightower totaled 57 rushing yards against two soft defenses. That cracked the door for Arrington to score twice last week; Arrington has had a season-high 11 touches in each of two of the past three games.

*Michael Jenkins, WR, Falcons: With Roddy White commanding so much attention, Jenkins is finding openings. He has at least 50 yards in five games in a row and has 11 catches over the past two weeks.

*Dustin Keller, TE, Jets: If you had been waiting to jump on the rookie, wait no more. Keller has 14 catches for 194 yards in his past two games and is an increasingly reliable part of the Jets' passing game.

*Bryant Johnson, WR, 49ers: With 56 yards and a score last week, Johnson had his first meaningful game since Week 2. If Josh Morgan misses a second game to his groin injury, Johnson could step up vs. the Cowboys.

*P.J. Pope, RB, Broncos: Do not let a week go by without thinking about a Broncos back. Peyton Hillis is getting the love for his two touchdowns, but he had just 10 carries. Pope had four -- and deserves more after averaging 8.8 yards a carry.
