Patterson appears to have a spot on Washington's initial 53-man roster, Nicki Jhabvala of The Washington Post reports.
The undrafted rookie out of Buffalo is one of three running backs left on the roster after Peyton Barber was released Tuesday morning, though it is possible Washington re-signs Barber after cutdown day (and thus avoids guaranteeing his salary). Even if Barber is brought back, the willingness to risk losing him suggests Washington is comfortable with Patterson in the No. 3 role. The rookie likely won't match Barber's contributions as a blocker or coverage man on special teams, but Patterson could get some touches on kick returns and would also offer a more explosive element if Washington ever needed to replace an injured Antonio Gibson or J.D. McKissic.
