Adrian Peterson said Thursday that he thinks he'll be able to play Sunday when the 4-7 Vikings host Buffalo. Peterson, who left last Sunday's Minnesota win over Washington with an ankle injury missed back-to-back days of practice, but didn't think the injury would sideline him further. An MRI Monday revealed a right ankle sprain.
"I'm going to be able to test it out (Friday) and I feel like I'll be ready to go," Peterson said, according to 1500ESPN.com.
Peterson has played in 48 consecutive regular-season games since sitting out in Weeks 11 and 12 of the 2007 season, Peterson's rookie year.
"Yeah, that's something I take pride in, especially at the running back position -- it's all about your durability, be able to last long," Peterson told 1500ESPN.
Rookie Toby Gerhart filled in for Peterson at Washington -- the former Stanford star carried the ball 22 times for 76 yards, both career highs. He also scored his first touchdown, a 5-yard run in the third quarter that put Minnesota ahead for good.
Part of Peterson's desire to play may correlate with Buffalo's extreme inability to stop the run. The Bills have the worst run defense in the NFL through Week 12 at 167.4 yards rushing allowed per game. The next closest team -- Arizona -- is allowing 146 yards per game.
