Woolfolk's father, Butch, a former Michigan All-American running back, told the Detroit Free Press that Troy sustained a dislocated ankle that had to be reset. There's possible ligament damage and a decision on surgery will be made later.
"[The coaches] said it happened during a tackle. His foot got stuck in the turf and his ankle just turned," Butch Woolfolk told the Free Press. "It was dislocated and when they put it back in the socket, they did an X-ray and found out about the ligament [damage] and the bone broke."
Jim Creech, Troy's high school coach spoke with both Troy and Butch on Tuesday night and told ESPN.com's Joe Schad that "it looks like [Woolfolk will] miss the season" with a dislocated ankle and broken bone in his leg, but could use a medical redshirt and return next season.
