Peterson suffered the ankle injury on his first rushing attempt last week, but played through it and finished with 20 carries and 103 rushing yards. Peterson said he "got it twisted up pretty bad" but didn't experience much swelling and has made progress this week with rest.
He said he doesn't expect the injury to hinder him as the Vikings play the Redskins on Sunday. Instead, he admitted he's played through worse ankle injuries before. While he said it's not necessarily a concern, he said he would like to get back to feeling good.
This week's game against the Redskins might have a little extra meaning for Peterson as it was against Washington he tore his MCL and ACL. Peterson suffered the injury when Redskins safety DeJon Gomes made a direct hit on Peterson's knee as he was going for a tackle.
When asked if he'd like to exact some revenge against Gomes this week, Peterson said "of course" and added he'll make sure to keep his shoulders low to deliver a blow.
