Another Auburn assistant coach may be on the move.

Auburn offensive line coach J.B. Grimes will interview for a position at Cincinnati, according to a source with knowledge of the discussions.

A source told AL.com that Grimes will interview with Cincinnati head coach and former Auburn coach Tommy Tuberville on Sunday. Grimes has coached with Gus Malzahn since 2012 when Malzahn was at Arkansas State.

Grimes' son, Nick, is a graduate assistant at Cincinnati.

Grimes' offensive lines have helped pave the way for one of the SEC's top rushing attacks over the last three seasons. Auburn was the first team in SEC history to lead the nation in rushing in 2013, and pass protection has led to rankings in the top four of the SEC in each of the last three years (sacks allowed).

Grimes is expected to leave the Auburn staff if officially offered a job, according to a source.

Grimes earns $370,000 per year and agreed in March to a contract extension through June 2017 at Auburn, according to paperwork obtained by AL.com.

Grimes had a cancer scare before the 2015 season. He underwent surgery to remove a cancerous spot on his tongue in late July. Doctors also removed his lymph nodes as a precautionary measure. A heavily bandaged Grimes returned to conduct practices with his offensive line six days later in early August.

"J.B.'s probably the toughest coach in college football," Auburn coach Gus Malzahn said at the time.

Grimes helped develop Greg Robinson into the second-overall pick in the 2014 NFL Draft. Center Reese Dismukes won the Rimington Trophy in 2014 and it's possible early entrant Shon Coleman could be drafted in the early rounds of the 2015 draft. Offensive lineman Avery Young has not yet announced whether he will forgo his senior season.

Potential candidates to fill Grimes' spot should he leave Auburn include Penn State offensive line coach Herb Hand, who is close friends with Malzahn. The two helped design offenses together at Tulsa as co-coordinators. Hand is credited with implementing zone-read concepts with Malzahn's Wing T spread.
