DENVER -- The NFL is looking into the March 6 arrest of Denver Broncos wide receiver Brandon Marshall on a misdemeanor battery charge for allegedly hitting his girlfriend.
NFL spokesman Greg Aiello confirmed the inquiry Wednesday but declined to comment further.
Fulton County, Ga., authorities say no formal charges have been filed. Marshall's lawyer was in a meeting and unable to comment.
Marshall's girlfriend filed an affidavit in Fulton County claiming Marshall hit her in the mouth and eye on March 4.
Marshall, who owns homes in Denver and Atlanta, was arrested March 6 and was released the following day after posting $1,000 bond.
It was the third arrest for Marshall in 12 months.
He is set to go on trial in September on a driving under the influence charge from October 2007. Marshall was arrested in downtown Denver hours after the Broncos beat the Pittsburgh Steelers 31-28.
He was also arrested in March 2007 on a false imprisonment charge after allegedly blocking a woman who was trying to leave his home in Colorado. The charge was dismissed after he completed anger-management classes.
