A UNC graduate assistant football coach was arrested early Monday morning on a charge of driving while impaired.

Durham police charged 28-year-old Gerald McRath with DWI. He was released on a $1,500 dollar bond.

McRath joined the Tar Heels football staff earlier this year as a Defensive Graduate Assistant Coach.

He played for Coach Larry Fedora while at the University of Southern Mississippi before being drafted by the Tennessee Titans in 2009.

He played for four seasons, but was suspended for four games in 2010 after testing positive for performance enhancing drugs.

McRath said at the time the positive test came from a tainted supplement.

Assistant Athletic Director for Communications Kevin Best told WCHL the university is aware of the incident and officials are looking into it.
