Umar Nurmagomedov warned by USADA

UFC lightweight prospect Umar Nurmagomedov (13-0) is now recovering from knee surgery.

“I had a missed doping test. They turned out to come in, I forgot. I wasn’t home, they knocked. And they gave me a flag.

I hope to start fighting in September. If I can fight from September, I think I’ll be back in October or November,” said Umar.
