Updated, 5 p.m.: The Washington Redskins announced the signing of place kicker John Potter on Saturday. Potter was brought on as an insurance policy for Kai Forbath, who is nursing a groin injury.

A decision on Forbath’s availability had yet to be made and, according to a person with knowledge of the situation, wasn’t expected to come until later Saturday or early Sunday when the Redskins face the Green Bay Packers on the road.

It wasn’t clear who the Redskins cut to make room for Potter on the 53-man roster. That move must come by 4 p.m.

Potter spent training camp and the preseason with Washington, but was used primarily as a kickoff specialist. He struggled on field goal attempts in practice and did not attempt one for Washington in a preseason game.

Potter appeared in six games for Buffalo last season, and kicked off but didn’t attempt any field goals.

Forbath made 17 straight field goals last season – a league record for first- year kickers – before missing his final attempt of the year. He made all of his field goal attempts during the preseason but missed a 40-yarder in the season opener.

It wasn’t clear how Forbath suffered the injury. On Thursday he talked about an eagerness to redeem himself for the miss. The Redskins listed him as questionable with the groin injury on Friday.
