Rapper P Diddy has been arrested and charged.
An 'unfortunate incident' is how the coach described it.
He was apparently hit with a weight-lifting kettlebell during an altercation at the University of California in Los Angeles, where P Diddy's son is on the football team.
The 45 year-old - whose real name is Sean Combs - claims he acted in self-defence on the football field.
But if convicted, he could face four years in prison.
