Diddy's recent head injury reportedly wasn't the result of an accident, but rather a prison fight with one of the most notorious inmates at FCI Fort Dix.

According to TMZ, the 56-year-old music mogul got into a physical altercation with Christopher "Dudus" Coke, a convicted Jamaican drug lord, during an outdoor recreation period at the New Jersey federal prison last Friday (Oct. 9).

Sources inside the facility told the outlet that Diddy "got the worst of it" during the confrontation, suffering a head injury that required him to be transported to an outside medical facility for treatment.

An ambulance was reportedly seen leaving Fort Dix around 1 a.m. Saturday (Oct. 10). Diddy returned to the prison before 7 a.m. and was reportedly conscious and communicating. His injuries were described as non-life-threatening.

The latest account contradicts an earlier explanation provided to Page Six, in which a source claimed Diddy "smacked his head on the bunk above him."
