Amari Cooper celebrated his first touchdown with a mock free throw before a 90-yard score that sent him to a Dallas Thanksgiving- record 180 yards receiving, and the Cowboys pulled even with Washington atop the division with a 31-23 win over the Redskins on Thursday.
Elliott ran for 121 yards with his TD and cash celebration as the Cowboys (6-5) won their third straight game since their first home loss, to Tennessee in the Dallas debut of Cooper. Dallas' eighth win in nine Thanksgiving games against Washington, and second in three years, earned a season split.
The Redskins (6-5) lost for the third time in four games in Colt McCoy's first start in four years coming off Alex Smith's season-ending leg injury.
The former Texas Longhorns star threw three interceptions to offset two touchdown passes. McCoy won his two previous starts at the home of the Cowboys, one for the 2009 Big 12 championship and the other his most recent NFL victory with the Redskins in 2014.
Cooper had 105 yards after the catch on his two touchdowns.
First, Cooper ran away from Quinton Dunbar after the Washington cornerback slipped on a short pass, turning it into a 40-yard TD for a 17-13 lead. Cooper celebrated by mimicking a free throw , shooting the football through the goal post.
On the 90-yarder, Cooper made the catch just outside the Dallas 30, spun out of the arms of Fabian Moreau and won the race to the pylon against former Alabama teammate Ha Ha Clinton-Dix, who tried to shove him out of bounds around the 5.
McCoy looked as if he hadn't started a game in a long time early, throwing into double coverage on his first play and fumbling while trying to scramble on his third, with the Redskins recovering and punting.
But McCoy settled in with a couple of third-down passes to Jordan Reed to keep drives going, then hit Vernon Davis in stride on a 53-yard touchdown - the longest Washington completion of the season - for a 7-7 tie.
The Cowboys were having all the fun before the Redskins pulled even, with Elliott scoring on a 16-yard run and dropping $21 into a giant Salvation Army red kettle behind the end zone. The cash was handed to him by a team photographer.
As a rookie in 2016, Elliott jumped into the kettle on the same part of the field after a touchdown in a 31-26 win over the Redskins. That season's NFL rushing champion, who wears No. 21, was fined for the stunt and later donated $21,000 to the Salvation Army.
After scoring on a scrambling 5-yard run for the third Dallas touchdown in less than eight minutes and a 31-13 lead, Prescott let Elliott help him into another kettle on the other end of the field, drawing the same unsportsmanlike conduct penalty Elliott did two years ago.
