Appalachian State quarterback Jamal Jackson practiced Monday and Tuesday, but it was not known by head coach Jerry Moore if the junior would be ready to play against No. 1 Georgia Southern Saturday.

Jackson injured his knee in the first quarter of Appalachian State’s 38-27 victory over Western Carolina Saturday, but could have returned if needed.

It wasn’t. Backup quarterback Logan Hallock took over the offense and completed 20-of-21 passes for 230 yards, two touchdowns and no interceptions. Hallock completed his first 20 passes before finally missing to Sean Price, who caught a Hallock offering out of bounds.

“He’s still day-to-day, but he’s a lot better (Tuesday) morning than he was (Monday),” Moore said. “It’s hard to say on Tuesday because he was out there in sweats. Just seeing him (Tuesday), his swelling has gone down, so we’ll just have to wait and see.”

Depth at quarterback suddenly became and issue Saturday since there really isn’t anybody behind Jackson and Hallock. Kameron Bryant is out with a knee injury and Kalik Barnes is serving a season-long suspension. Freshman Paul Magilore is redshirting.

Moore said he had confidence in Hallock, who also has played receiver at Appalachian State after playing quarterback at West Wilkes High School. Hallock was also the holder on place kicks last season.

“Logan’s good,” Moore said. “He’s played receiver and quarterback and everybody on the team has respect for him, so that’s a big plus for us.”

Jackson started against Western Carolina, and led Appalachian State to a 7-0 lead. Hallock took over when Jackson got hurt, and ASU finished the drive with a 28-yard Sam Martin field goal.

In the second quarter, Hallock found Price for a 36-yard gain that led to a 4-yard touchdown run by Steven Miller, which gave the Mountaineers a 17-0 lead. Hallock added an 18-yard touchdown pass to Price, which put Appalachian State in front 24-7 by halftime.
