Adrian Peterson was questionable heading into the Washington Redskins' Monday night game against the Eagles. The 33-year-old back has been battling a shoulder injury since early October, but he looked like his old self when he broke through a gap and went 90 yards to the house. He became the oldest player in NFL history with a 90+ yard rushing touchdown.

The play came on Mark Sanchez's first snap for Washington after Colt McCoy left with a fractured right fibula in the second quarter.

McCoy was filling in for Alex Smith, who suffered a compound fracture and a spiral fracture to both the tibia and fibula in his right leg when he was sacked by Kareem Jackson and J. J. Watt.

Peterson led all rushers entering the fourth quarter, but was stymied apart from the big run. On nine rushes, Peterson had 98 yards, meaning he averaged just one yard per carry outside of the touchdown.

Big plays were always a staple of Peterson's game in Minnesota, and that has remained true in Washington.

In his first season with Washington, Peterson has started all 12 games and is on pace for the eighth 1,000 rushing yard season of his career. It would be his first 1,000-yard season since 2015.

However, more than a third of Peterson’s 758 rushing yards have come in two games. He rushed for 120 yards versus the Packers in Week 3 and 149 yards versus the Giants in Week 8.
