Morris rushed for 200 yards and scored three touchdowns against the Cowboys, all while breaking Clinton Portis' franchise single-season rushing mark. On the year, Morris finished with 1,613 yards on the ground.
Last week marked the seventh time Morris eclipsed the 100-yard mark but was the first occasion which he ran for 200 yards. His previous career-high was against the Baltimore Ravens on Dec. 9 when he rushed for 129 yards in the Redskins' victory.
Morris ended the regular season averaging 4.8 yards per carry which puts him at ninth in the league and second in the NFL only behind Adrian Peterson in rushing yardage. He also led the NFC with 22 broken tackles and 13 rushing touchdowns.
The Redskins will now host an NFC Wild Card game against the Seattle Seahawks on Sunday.
