The rapper, whose given name is David Darnell Brown, was accused in a complaint of stabbing Jimmy James Johnson in retaliation after Johnson allegedly punched Brown's mentor, Dr. Dre (search), during the taping of the show on Nov. 15.
Dre, a producer and rap star whose name is Andre Young, was about to receive a lifetime achievement award when he was hit.
The attack set off a brawl that spread through the crowd. Police issued an arrest warrant for Brown, 23, after authorities identified him on a videotape recorded during the awards show.
Brown surrendered to police Nov. 19 and was freed on $500,000 bail. If convicted, he faces up to eight years in prison, authorities said.
The District Attorney's Office also filed an assault charge Monday against Johnson, 26, who is in custody on a parole violation.
Young Buck is signed to Dre's record label as part of the G-Unit clique, and his first solo album, "Straight Outta Ca$hville," debuted at No. 3 on the Billboard charts in August.
