EDEN PRAIRIE, Minn. (AP) -- Minnesota Vikings running back Adrian Peterson is listed as doubtful for Sunday's game at Atlanta because of a high ankle sprain.
Peterson hasn't practiced all week after hurting his left ankle in last week's game in Oakland. He was carted off the sideline Sunday and had been in a walking boot for three days this week. Peterson is sixth in the NFL in rushing with 872 yards. He's tied with Philadelphia's LeSean McCoy with a league-leading 12 touchdowns.
Toby Gerhart, the 2009 Heisman Trophy runner-up in his senior season at Stanford, would start in Peterson's absence. Minnesota coach Leslie Frazier said Lorenzo Booker could also see some time at running back.
