Minnesota Vikings star running back Adrian Peterson has left the game against Oakland with an ankle injury.
Peterson hobbled off the field at the end of the first quarter after a tough 12-yard run through heavy traffic. His left ankle rolled hard as he was brought down by the Raiders, and he could barely put weight on it as he was helped to the sideline by team trainers. Peterson grimaced on the table while his ankle was looked at and rode on a cart to the locker room for further examination.
Peterson entered the week fifth in the NFL in rushing with 846 yards. He scored his 11th rushing touchdown before he got hurt.
The Vikings said his return was questionable.
