Choice will miss the Nov. 1 game against Virginia Tech, but his status for the rest of the season is not known, according to coach Chan Gailey.
Choice led the Atlantic Coast Conference in rushing in 2006. The senior again leads the ACC with his average of 108 yards rushing despite leaving the Army game in the first quarter after the right knee injury. He needed help leaving the field and was carted to the locker room.
