Meanwhile, star wide receiver Randy Moss is only expected to see limited action on Sunday because of a similar injury.
Ankle injuries are very difficult to be able to predict.
Bennett, a No. 1 draft choice, has struggled to replace Robert Smith as Minnesota's top running back. He has rushed for 214 yards this season and has yet to score a touchdown. Moss originally sprained his right ankle playing basketball prior to minicamp in 1998 and the injury flared up again during this past Sunday's 31-26 win over Detroit. It's very difficult to play at your best if you are not 100 percent health-wise. We're going to do everything we can to get him as close as possible to 100 percent because it's going to be that type of a ballgame this week.
