Peterson, 35, rushed for 1,940 yards and 12 touchdowns in two seasons with Washington. He missed one game, when then-coach Jay Gruden made him a healthy inactive for the 2019 season opener.
Peterson, who entered the league in 2007, is fifth on the NFL’s career rushing list with 14,216 yards — just 1,053 behind No. 4 Barry Sanders — and fourth in rushing touchdowns with 111.
Peterson still wants to continue playing, a source told ESPN’s Adam Schefter.
