he Trail Blazers' bench could be a man down when they visit the San Antonio Spurs on Wednesday night.

Mo Williams, the team's Sixth Man, is listed as questionable with a right hip strain.

The veteran backup point guard injured himself Tuesday night in the second quarter of the Blazers' 109-99 loss to the Memphis Grizzlies. With 5:26 left in the first half, Williams ran around a screen on the perimeter and charged toward the basket, nailing an 8-foot floater in the lane.

He appeared to hurt himself when he landed, however, as he grimaced and rubbed his hip shortly afterward. Williams left the game 34 seconds later and went directly to the locker room with Chris Stackpole, the Blazers' director of health and player performance.
