Appalachian State starting quarterback DeAndre Presley is questionable for Saturday's game at The Citadel, Mountaineers coach Jerry Moore said Tuesday.

Presley bruised his right throwing shoulder against Wofford on Oct. 1 and has not participated in a practice since then. The six-time defending Southern Conference champion Mountaineers had a bye last weekend.

"He is a very, very questionable player," Moore said.

Presley finished third in the voting for the 2010 Walter Payton Award (sponsored by Fathead.com) last season, but the All-America senior has not played as well this season during Appalachian State's 3-2 start, including 1-1 in the SoCon.

Redshirt sophomore Jamal Jackson, from Atlanta, is being prepared for a possible first career start. Moore said the 6-foot-3, 205-pounder had surgery this past spring to repair a punctured lung.

Jackson saw time in Appalachian State's 39-10 win against The Citadel last season, gaining 23 yards on seven carries with an interception on his only pass.

"Jamal is a guy that we have a lot of confidence in him. He grew up in the spring," Moore said.

"We just have to wait and see how he performs and if he's the guy on the field. There's always the chance that DeAndre will be healthy by then."

The Citadel is 2-3 overall and 1-3 in the SoCon
