The Vikings signed Dallas to the practice squad and elevated him to the active roster Saturday.
Dallas was released by the Vikings on Friday due to the impending return of Jordan Mason (thumb) from injured reserve. Dallas has opted to remain with Minnesota as the member of the practice squad, and he'll be on the 53-man roster for Sunday's game against the Colts, when he'll serve as the RB4 behind Mason, Aaron Jones and Demond Claiborne.
