According to TMZ.com, dude is a barbershop owner in Los Angeles who is friends with the man Knight was trying to defend in the now infamous altercation outside of Hollywood's Shag nightclub.

       The brawler, who would not give his name, yet is pictured on TMZ, says he was playfully arguing about money with the mutual friend when the former music mogul misunderstood and thought it was serious.       

       When Suge tried to defend his friend, fisticuffs jumped off and the barber – all of 5'10" and 173 lbs – delivered the punch that knocked 6'3", 315 lb Knight unconscious for a good three minutes, according to the Web site.

       Meanwhile, the author of a new book about Knight's former Death Row partner, Dr. Dre and West Coast hip hop, fears a war may have been started by the knockout punch.

       Bruce Williams, whose book "Rollin' With Dre" is in stores now from Ballantine/Random House, said in a statement Monday: "Although it goes against my gut feeling of how he’ll handle this situation, I hope and pray that Suge doesn't do anything stupid and lets this thing go."       

        “Suge Knight has long been someone who has no problems using violence to handle business," Williams stated. "I’ve seen what he’s capable of first-hand and wrote in detail about some of these instances in my book, 'Rollin' With Dre.' It’s unfortunate that this incident has occurred because it is likely that more people will want to test Suge to make a name for themselves, which in turn means more violence.       

       "Although I’m sure there are countless people who are relieved to see something like this happen to Suge, all it means to me is retaliation is almost certain. The fact that Suge did not bother to press charges against his assailant makes me certain of it."
