Reggie Bush was back on the practice field for the Detroit Lions on Friday, doing limited work.

But that doesn't necessarily mean Bush, who suffered a knee injury last week against Arizona and missed Wednesday and Thurday, will be in the lineup when the Lions face the Washington Redskins on Sunday.

In fact, FoxSports Detroit says Bush, who is listed as questionable on the injury report, could wind up being a game-time decision for the Lions.
