UFC light heavyweight champion Jon Jones suffered a torn left meniscus and sprained ankle in training earlier this week, postponing his fight with Daniel Cormier from Sept 27 to Jan 3.

In an interview with Tristen Critchfield for Sherdog, Jones’ coach Greg Jackson said the injury occurred during a takedown attempt by UFC heavyweight Alistair Overeem.

It’s part of the game,” said Jackson. “It wasn’t like … somebody went for a flying kick and dislocated it. Somebody went for a takedown, [Jones] stepped the wrong way, twisted the wrong way and down he went. He was fighting it, and he just twisted it. And then it just popped.

“Alistair’s maybe 240, Jon’s 220. It’s not like he was working with a giant moose. It was just one of those things.”

The important thing is I know [what happened]. I know he’s not ducking [Cormier]. I was there when the injury happened. That’s all I need. There’s always theories. That’s sports; that’s entertainment.

Jones plans to remain in New Mexico and will try to train around the injury.
