Minnesota Vikings running back Adrian Peterson suffered a mild ankle sprain in Sunday's victory over the Tennessee Titans, but shouldn't be in danger of missing any time, according to 1500 ESPN's Tom Pelissero.

The injury, which occurred on the second play of the game, hampered Peterson through the remainder of the first half, as he told FSN North's Brian Hall:

"I was thinking about it too much. I couldn't cut and I was trying to test it out. That threw my focus off."

After rushing for just 35 yards in the first half, Peterson finished a bit stronger, ending his day with 88 yards on 17 carries. While Peterson believes he played better in the second half, he still seemed down about his overall effort.

I just had to come in in the second half and get some tape and adjust and refocus. I came out and did all right in the second half, but I just got to do better."

As a whole, the Vikings ran the ball very well on Sunday, racking up 175 yards on the ground, albeit against the league's 27th-ranked run defense. Minnesota will face a stiffer test on Oct. 14, when they face the Washington Redskins, who are ranked No. 13 in the NFL in rushing yards allowed.
