Richt's top running back at Miami arrested, suspended

Mark Richt has been Miami's head coach for less than five months but he's now dealing with the fourth arrest of a Hurricanes player in his short tenure.

The school suspended standout running back Mark Walton indefinitely Saturday after the player was arrested on suspicion of driving under the influence in Coral Gables, Fla.

Walton's arrest comes a week after Richt, Georgia's former coach, urged his players to help each other stay out of trouble and avoid negative headlines.

Richt is in his first season as the Hurricances coach after being fired by UGA in November.

The Associated Press reported Walton was also under investigation for impersonating a law enforcement officer, a third-degree felony in Florida.

Walton led Miami with nine rushing touchdowns and 10 total touchdowns as a freshman last season.

"We are aware of the situation regarding Mark Walton and we have taken immediate action by suspending him from the team," Miami athletic director Blake James said in a statement released by the university.

Miami offensive linemen Jahair Jones and Trevor Darling were arrested in March, but both had their charges dropped. Kicker Jon Semerene was arrested in a DUI incident in March as well and he was dismissed from the team.
