Texas A&M sophomore safety Justin Dunning went out of practice on Monday with an undisclosed injury, according to the The Eagle.
It is unclear at this point how long Dunning will be out. Kevin Sumlin told reporters after practice that the team is still diagnosing the true sophomore.
Dunning is expected to be a key reserve at safety and nickel on a shallow Aggie defense. He posted 20 tackles and a pass defended in 11 games as a true freshman. He was rated the No. 134 overall player and No. 6 safety in the class of 2015.
