The mighty O.J. fell at the hands of skinheads. Did it happen or not? O.J. says yes (and I have the boo boo's to prove it). Prison officials say "I didn't see nuthin" (just some good ole boys havin fun with the juice).

The National Enquirer reported on Tuesday that O.J. Simpson was attacked in the Nevada prison and beaten unconscious. The paper said he spent three weeks in the infirmary:

Inmates cheered as a muscular young skinhead knocked him to the ground, punching and kicking him to a bloody pulp and inflicting injuries so severe he secretly spent nearly three weeks in the infirmary before he recovered.

According to the report, prison authorities have "done their best" to keep the beating a secret and Simpson is now afraid to leave his cell.

The 63-year-old has reportedly been a "marked man" in prison "ever since white supremacists overheard him brag about his sexual conquests of beautiful white women."

Simpson's former business partner, Bruce Fromong, told the paper: "Unfortunately for O.J., a group of young skinhead punks were within earshot - and they were enraged."
