LAS VEGAS (AP) -- UFC heavyweight Alistair Overeem has been denied a license to fight in Nevada after failing a drug test and pulling out of a championship bout next month.
Overeem told mixed martial arts regulators in Nevada that a doctor-prescribed anti-inflammatory caused him to fail the test.
The Nevada Athletic Commission on Tuesday ruled that the Dutch kickboxing champion can't reapply for a license until late December.
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 that knows he should know what's going into his body.
The fighter apologized in a statement released by his managers.
