From what Sherdoggers mentioned earlier and from what I know
Randy (Sylvia), Tito (Bader), Wandy (Bisping and Stann), Minotauro (Schaub), Hendo (Shogun, Boestch and Lombard), Hardy (Amir), Hughes (Almeida), Belfort (Bisping and Rockhold), Bisping (Rockhold), Cruz (Dillashaw), Romero (Weidmen),
many more I'd imagine.
