While Adrian Peterson has already proven his toughness, his latest ankle injury should put some doubts in the minds of fantasy owners around the world.
The Minnesota Vikings running back returned from a torn ACL injury that he suffered at the end of last season to play on opening day. His latest injury is not as severe, but it could end up costing him more time.
Since I twisted it up and it happened, it's been hurting consistently. Then we go out and play, it re-aggravates it, just the cutting and different things you're doing out there. So, it's sore, but you've just got to push through it.
It was a little worse, waking up that Monday and just feeling the beating you put on it the previous day. It wasn't already healed 100 percent going into the game.
The running back had a pretty impressive performance considering he was not healthy. He totaled 129 yards from scrimmage, topping the 100-yard mark in his fourth straight game.
Unfortunately, injuries of this nature are unlikely to go away. He admitted that he re-injured his ankle during his latest game. This will probably continue in every game he plays until it gets worse.
This situation has already kept him limited this week. Joe Oberle of CBS Sports reported that Peterson has missed both practices and is questionable for this Sunday's game.
Even if he does play, it is unknown how effective he will be. The matchup this week against the Arizona Cardinals is not as good as it initially seems. While the Cardinals have the No. 19 run defense in the NFL, the unit moves up to 15th in yards against per carry. Additionally, the defense has only allowed three touchdowns on the ground all year.
Getting into the end zone has been a problem for Peterson this year after excelling at it throughout his career. ESPN Stats and Info tweeted an interesting statistic:
Since scoring 2 TDs in Week 1, Adrian Peterson has not scored a rushing TD in any of his last 5 games, the longest streak of his career.— ESPN Stats & Info (@ESPNStatsInfo) October 17, 2012
Peterson is still getting the yards, but he will severely hurt fantasy owners if he is unable to break this streak and score some touchdowns.
He will hurt his team even more if he re-injures his ankle against the Cardinals.
The two-time All-Pro has been a pleasant surprise in fantasy this season. However, his long-term prospects will start to fade if his ankle becomes an issue.
