Washington (ankle) is listed as doubtful for Sunday's game against the Eagles, the Detroit Free Press reports.
Absent from practice all week, Washington is highly unlikely to play in Sunday's game, just one week after suffering what appeared to be a pretty severe ankle sprain. Assuming the rookie does in fact sit out, Theo Riddick and Zach Zenner will split the backfield work, with the former likely to get more snaps and touches, though the latter could get goal-line carries. Michael Burton, a fullback by trade, could perhaps also be in the mix or a few touches.
