Banged-up running back Clinton Portis will be a game-time decision for the second straight week for the Washington Redskins.

Bet NFL Week 4
Portis is nursing a bruised calf after getting kicked in the second half of last week's loss to Detroit. He's also been hindered by bone spurs in both ankles, but coach Jim Zorn said Friday the calf is the reason he feels Portis has a ``50-50'' chance of playing Sunday against Tampa Bay.
Portis is off to one of the slowest starts of his career, with 183 yards on 47 carries through three games for the Redskins (1-2).
Ladell Betts and Marcus Mason shared the first-team snaps at running back during Friday's practice.
Defensive tackle Albert Haynesworth (strained hip muscle) and fullback Mike Sellers (bruised thigh) returned to practice.

Oddsmakers from online sports book Sports Interaction have made the Redskins 7.5-point favorites over the Buccaneers in Week 4. The over/under total for the game has been established at 37.
