In an interview with AuburnSports.com, Kelly said Rollison made his decision to be closer to home.
Rollison was considered one of Auburn's biggest signees during Auburn coach Gene Chizik's first recruiting class. He competed for the backup quarterback job well into August before ultimately losing the battle to Neil Caudle. Rollison still worked with the varsity offense all year instead of practicing with the scout team, as most redshirt players do.
He had a misstep in December when Chizik suspended him for the Outback Bowl because of an unspecified violation of team rules. That move immediately preceded Auburn's decision to recruit and ultimately sign JUCO QB Cam Newton, who is largely considered the favorite to win the starting job.
Rollison was still supposed to compete for the starting position during the spring.
Kelly did not mention Newton or the quarterback race during his interview with AuburnSports.com, nor did he say anything about it to ESPN's Joe Schad.
Auburn has not yet confirmed that Rollison has or will leave the program.
