Both men were charged with assault after a Maryland man said they punched him outside a Washington hotel in October. Christopher Hollosy was found guilty on Monday and is appealing.
Hollosy had told police he punched the man after the man tried to get on Brown's tour bus. The man said Brown and later Hollosy punched him after he tried to get in a photo Brown was taking with two women.
Court papers say the man's nose was fractured. Brown has denied hitting the man.
A judge in Los Angeles has denied a request to release R&B singer Chris Brown from custody while he awaits trial on an assault charge in Washington, D.C.
In Los Angeles, Superior Court Judge Victor Greenberg denied a request Wednesday by Brown's lawyer to release Brown from custody either on bail or his own recognizance, The Associated Press reported. The singer has been jailed since mid-March on a no-bail warrant after he was expelled from a court-ordered rehab program.
He remains under court supervision in Los Angeles for his 2009 attack on then-girlfriend Rihanna and was jailed in the DC area while awaiting trial there.
