Potter will presumably kick off and handle extra points and field goals if Washington’s regular kicker, Kai Forbath, is unable to play in Sunday’s game at Green Bay because of a groin injury.
Adding Potter means Washington would have to release or waive someone to stay at the 53-player roster limit.
The 23-year-old Potter was a seventh-round pick of the Bills in 2012 and was Buffalo’s kickoff specialist for six games. Potter played in two preseason games with Washington this summer.
Potter has not attempted a field goal or extra point in an NFL game. He connected on 47-of-65 field goals in four seasons at Western Michigan from 2008-2011.
