WASHINGTON - Kirk Cousins tied his career high with four touchdown passes, including two to tight end Jordan Reed, and ran for another score as the Washington Redskins defeated the Buffalo Bills 35-25 on Sunday to remain atop the NFC East.

Wide receiver DeSean Jackson caught six passes for 153 yards, including a 77-yard score for the Redskins (7-7), who posted consecutive wins for the first time since Weeks 7-8 of last season.

Washington closes the season with road games at Philadelphia and Dallas.

Cousins completed 22-of-28 passes from 319 yards, with no interceptions. Reed had seven catches for 84 yards.

Quarterback Tyrod Taylor hit on 16-of-27 attempts for 235 yards and two touchdowns for Buffalo (6-8), which has lost four of five games and saw its already slim playoff hopes extinguished.

The Bills lost running back LeSean McCoy (10 carries for 29 yards) to a right knee injury early in the second half.

Trailing 28-3 after Jackson's 77-yard catch and run for a touchdown early in the third quarter, Buffalo scored two quick touchdowns.

First, running back Mike Gillislee ran 60 yards for a score, and then Taylor found wide receiver Sammy Watkins behind two defenders for a 48-yard strike with 3:56 left in the quarter.

Washington responded by marching 80 yards in 13 plays. Cousins capped the drive with a 5-yard touchdown pass to wide receiver Pierre Garcon with 11:16 left to play.

Cousins has 16 touchdown passes and just three interceptions over his past eight games.

Watkins had five catches for 111 yards and two touchdowns

Washington outgained Buffalo 257-93 in the first half and scored touchdowns on their first three possessions for the first time since September 19, 1999 (against the Giants).

Cousins was 6-of-6 for 73 yards - including a 28-yard completion to Jackson on Washington's opening drive.

Reed had three catches, capping the drive with a 3-yard touchdown catch.

On their next possession, the Redskins gambled on fourth-and-one from the Buffalo 37, and were rewarded when Buffalo was called for encroachment.

Cousins then hit Jackson for 27 yards to the five. On third-and-goal from the 13, Cousins rolled right, ran, and was hit inside the 5, but dove into the end zone.

Washington went up 21-0 when Cousins hit Reed for an 18-yard score.

After Washington's Jamison Crowder fumbled a punt, the Bills drove to a first-and-goal at the 5. But McCoy failed to get in three times from inside the one (one was negated by a Washington penalty) and Taylor threw incomplete on fourth down.
