After sitting out practice this week because of a calf injury, top running back Clinton Portis could miss Sunday's game against the Tampa Bay Buccaneers at FedEx Field, Coach Jim Zorn said.
"He's just questionable. That's all. Fifty-fifty," Zorn said after practice today at Redskins Park.
Portis did not take any reps in practice this week. Ladell Betts and Marcus Mason split the first-team reps, and Zorn said Mason would be active this week. If Portis sits out, Anthony Alridge would be the team's fourth active back, joining Betts, Mason and special-teams standout Rock Cartwright.
