Here is ESPN's highlight video from the monumental UFC on FOX card that featured the heavyweight championship bout between Cain Velasquez and Junior dos Santos. It shows a few portions of the fight, but it doesn't show the key moments, so I do suggest catching the entire fight as a whole.
It didn't last that long, but here's the entire play by play from our live blog of the bout:
Round 1: HERE WE GO! The energy is insane. Cain lands a leg kick. Right hand from JDS. Junior tries a front kick and is nearly taken down. Body punch from Dos Santos. Cain looking to attack the lead leg. HOLY CRAP! Junior lands a ridiculous overhand that drops Cain. Junior swarms and lands several punches. Cain looked out and Big John steps in and stops the fight.
Official Result: Junior Dos Santos via Knockout at 1:04
