I believe this happened on a Bully Beatdown episode. The bully knocked down the professional fighter then the pro head kicked the bully (which was against the rules). The fight was stopped and the pro fighter was immediately DQ but at the end the bully said the pro fighter won the fight and turned down the prize money.
It's not landing on Aldo, Jones or GSP but it's a novice/untrained dropping professional fighter. Jake Shields was on Bully Beatdown FFS.
