VIDEO: Overeem wrecks Dos Santos in co-main event at UFC on FOX 17

Alistair Overeem is smuggling C-4 inside his fists, and it detonated on Junior dos Santos' chin.

After nearly two rounds of what can only be described as an aggressive staring contest, Overeem, who was outpointing Dos Santos with intermittent low kicks and a scant few combinations, sent the former UFC heavyweight champion crashing to the canvas with a scintillating left hook.

Overeem immediately pounced on his stunned foe, landing a few coffin nails until referee Dan Miragliotta stepped in to stop the carnage.

A potential free agent, Overeem could be looking at a massive payday and a title shot in his future.
