Rob Emerson's claim to fame these days is having been named by Ian McCall as the man who slept with McCall's wife. He currently fights in Bellator, however, he did have a UFC run coming out of The Ultimate Fighter 5, where he lost to Gray Maynard in a Fight of the Night bout at the finale.
Back in his UFC run, the highlight was no doubt his 12-second knockout of Manny Gamburyan at UFC 87. Gamburyan is no slouch, and has had gone on to have the better career of the two, leaving the UFC for the WEC then returning to the Zuffa fold when they purchased the fight promotion and its exciting lighter weight classes.
