A man accused of punching Dr Dre at the hip hop Vibe Awards last November must stand trial on an assault charge, a judge has ruled.
Dr Dre had been due to receive an award at the ceremony
Judge James Dabney said sufficient evidence had been found against Jimmy James Johnson, 26.
Mr Johnson allegedly punched Dre, whose real name is Andre Young, after asking for his autograph.
The incident sparked a brawl, during which Mr Johnson was allegedly stabbed by rapper Young Buck.
Mr Johnson suffered a collapsed lung. The brawl spread to involve many of the 1,000-strong crowd.
Buck, whose real name is David Darnell Brown, has pleaded not guilty and is on bail awaiting trial.
Dre, 40, had been about to receive a lifetime achievement award when he was punched.
Mr Brown is signed to Dr Dre's record label as part of G-Unit. His debut solo album, Straight Outta Cashville, went in at number three on the US Billboard chart in August.
