Adrian Peterson typically holds his weekly press conference on Thursdays but it's unclear if he will be available today because of his ankle injury.
Peterson did not practice Wednesday because of his right ankle injury and has been getting treatment several hours a day this week.
If Peterson can't play Sunday against Buffalo or is limited, the Vikings probably gained more confidence in rookie Toby Gerhart, who did a solid job in relief against Washington this past Sunday.
Gerhart set career highs in carries (22) and rushing yards (76) and scored his first NFL touchdown.
"If I'm called upon to carry the ball again, 20 plus times or whatever it may be, I'm looking forward to that," Gerhart said.
Gerhart had 24 carries total in the first 10 games. He had 17 carries for 63 yards in the second half Sunday. He said he felt it when he woke up on Monday. "I felt like I did back in college when I was carrying it 30 times a game," he said. "Everything was sore and basically just fell out of bed. But I sat in the cold tub the last two days and feeling better." Gerhart has mainly been used on third downs this season so he said the extra work allowed him to get into a better rhythm. "I think for any running back, the more touches you get you kind of get a sweat going, you get a feel for the game, you get a feel for how the defense is playing," he said. Gerhart said he feels strong physically at this point in the season because he hasn't had a lot of work. He said his performance last week helps his confidence going forward. "I always believed that I can play at this level," he said. "It's just my opportunities have been limited. It was nice to get out there and perform OK, perform well and help this team win."
