After sitting out of Saturday’s scrimmage in part to rest but also to allow the coaching staff to assess the backups in greater detail, Maryland starting quarterback C.J. Brown is back at practice this week working with the first team.

Brown was held out of the scrimmage after a heavy workload over the first several weeks of training camp in College Park. The redshirt junior estimated he has thrown 300 passes since camp opened, and it led to some arm fatigue.

“They’ve been keeping track of how many balls I’ve thrown, and my arm was kind of bothering me a little bit,” Brown said following Tuesday afternoon’s practice. “Just take a rest, take a break from it a little bit. I had a practice off, and they decided not to scrimmage me.”

Brown has not been in uniform for a game since November 2011. He was ready to take over the starting job last year, but a torn ACL in training camp left him on the sideline for the entire season. The injury occurred during a non-contact drill, and Brown only last month was cleared to practice without a knee brace.

While Brown has been growing more comfortable with a new cast of wide receivers and tight ends, the competition behind him at No. 2 quarterback remains unresolved less than two weeks before the Terrapins open the season against Florida International at Byrd Stadium.

Sophomores Caleb Rowe and Perry Hills started games last season, but each had his season cut short because of an ACL injury. Also in the mix is Ricardo Young, who transferred from New Mexico and sat out last season.

“Nobody’s really separated themselves,” Coach Randy Edsall said. “It’s really Caleb and Ricardo. Perry’s probably down. I think Perry’s probably still coming back a little bit from that knee injury, but that’s where we are. I waiting for somebody to step up. If not, then we’ll just make a week-to-week decision or a situation-to-situation decision.”
