Dallas reverted to the Vikings' practice squad Monday, per the NFL's transaction log.
Dallas carried the ball one time for four yards over 17 offensive snaps in Sunday's game against the Lions. The running back also participated in 17 snaps for the special teams unit. Dallas has one elevation to the active roster remaining before the Vikings will be forced to re-sign the 28-year-old to the 53-man roster to get any more snaps out of him.
