Snoop Dogg has told jurors he did not strike a fan, who is suing him for $22m (£15.1m), with a microphone with a knuckleduster-style handle at a gig.
The artist, real name Calvin Broadus, said he went straight to his tour bus after Richard Monroe Jnr jumped on stage and was challenged by security.
Mr Monroe has told the Santa Monica court he was “left for dead” by security at the 2005 Seattle gig.
A 12-person jury must decide if Mr Broadus should compensate Mr Monroe.
The best way for the injuries not to have occurred was for him to stay in his seat and enjoy the show like the rest of the fans

Mr Monroe says that, as Mr Broadus launched into his hit, Gin and Juice, he thought the rapper had called on fans to get up on the stage.
Lawyers for Mr Broadus have said Mr Monroe should not have gone on stage and that security staff thought the rapper was being attacked.
