LAS VEGAS (AP) — UFC heavyweight Alistair Overeem plans to tell mixed martial arts regulators in Nevada that a doctor-prescribed anti-inflammatory caused him to fail a drug test and pull out of a championship bout next month.

The Dutch kickboxing champion was expected before the Nevada Athletic Commission on Tuesday.

Overeem says he aggravated a rib injury on his left side before a press conference in March for UFC 146. He says his doctor prescribed an anti-inflammatory that was mixed with testosterone.

He says he didn’t know about the mix but knows he should know what’s going into his body.

The fighter apologized in a statement released by his managers and says he’ll do whatever it takes to prove he’s a clean fighter.
