LANDOVER, Md. (AP) -- Kirk Cousins found a groove and undrafted rookie running back Robert Kelley made the most of his chance and the Washington Redskins beat the Buffalo Bills 21-16 Friday night in the third preseason game.
With the Bills (1-2) resting almost their entire starting defense, Cousins overcame a rough start to finish 12 of 23 for 188 yards, three touchdowns and an interception.
Despite coming mostly against Buffalo's second- and third-stringers, it was an important recovery for Cousins, who had thrown only five passes in the preseason and didn't play last week in an effort to test backup Colt McCoy.
Kelley ran for 51 yards on 12 carries in a personal showcase with Matt Jones and Chris Thompson out and after seventh-round pick Keith Marshall sprained his left elbow on his only carry of the game.
Bills starting quarterback Tyrod Taylor played only two series, by coach Rex Ryan's design, going 2 of 5 for 11 yards before being replaced by E.J. Manuel.
Ryan also opted to rest running back LeSean McCoy and several key defenders, including defensive tackle Kyle Williams, linebacker Jerry Hughes and cornerbacks Ronald Darby and Stephon Gilmore.
Coach Jay Gruden took a more conventional dress-rehearsal approach to the third preseason game for the Redskins (2-1) and got the kind of performances he'd like to see from top players such as tight end Jordan Reed, receivers DeSean Jackson and Pierre Garcon, left tackle Trent Williams and cornerback Josh Norman.
Reed, Garcon and receiver Ryan Grant each caught a touchdown pass from Cousins, and Norman looked sharp on defense along with second-year linebacker Preston Smith and lineman Ziggy Hood.
