Roy Nelson knocked out Bigfoot Silva then kicked the ref after extremely late stoppage

He wasn't ready.

"Big Country" Roy Nelson rocked "Bigfoot" Antonio Silva with a nasty right uppercut and wailed on the downed heavyweight before referee John McCarthy eventually stopped the fight much too late at UFC Fight Night Brasilia.

Nelson at one point pauses in the beatdown to look at McCarthy waiting for a stoppage that wouldn't come for a bit. After finishing Silvia, Nelson was clearly irritated and let McCarthy know with a quick kick to the butt.

After frustrations emerged following a quick stoppage at UFC 203, it looked like McCarthy was trying to give Silva enough time to defend himself. Unfortunately it was way too much time.
