US rapper Young Buck has pleaded not guilty to an assault charge for allegedly stabbing a man at the Vibe hip-hop awards in the US in November.
Young Buck is part of rapper 50 Cent's crew G-Unit
Buck, 23, whose real name is David Darnell Brown, is accused of stabbing Jimmy James Johnson, who allegedly punched rap star Dr Dre at the awards.
The alleged incident sparked a crowd brawl as the show was being recorded.
Mr Brown faces up to eight years in prison if convicted, authorities said.
He was freed on $500,000 (£257,000) bail on 22 November last year, a week after the awards took place.
Dr Dre accepted his award after the incident
On Monday Mr Johnson, who suffered a collapsed lung following the stabbing, pleaded not guilty to an assault charge for allegedly hitting Dre in the face after asking for an autograph.
Mr Brown is expected back in court on 18 February, when a date is expected to be set to determine if there is enough evidence for a trial.
Dre, who had been about to receive a lifetime achievement prize just before the brawl broke out, is also mentor to Mr Brown, who is signed to Dre's record label as a member of 50 Cent's G-Unit crew.
Mr Brown's first solo album as Young Buck, called Straight Outta Ca$hville, debuted in the US Billboard chart at number three in August.
