Snoop Dogg said he went to his tour bus and did not strike Mr Monroe Jnr
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.
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.
Screen shots taken from video footage of the incident, at the White River Amphitheatre, were shown in court on Monday and Mr Broadus identified performers and security staff near the struggle.
Mr Broadus said a number were affiliated with fellow rapper The Game, who was performing on the tour.
"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 Broadus said.
Lawyers for Mr Monroe challenged the rapper's recollection of the incident.
The judge did not allow their attempts to ask Mr Broadus if he had taken drugs that night.
Mr Monroe, who first brought the action in 2006, says he was hit by Mr Broadus with a microphone and attacked by his security.
He told jurors on Friday: "I was getting punched, kicked, kicked, punched. It was brutal. I was really in shock. I couldn't believe it."
Mr Broadus has released nine studio albums, with three going to number one in the US.
His hits include Who Am I (What's My Name?), Drop It Like It's Hot and Signs.
