I remember them promoting "Cowboy vs Cowboy" as a main event some time ago, but don't remember the fight. Edit - Just checked, I'm getting my Oliveiras mixed up, ignore that. Edit 2 - He was beaten by Holloway in a fight night main event in August 2015, in the first round. Lost by "neck injusy" though. My memory is shocking, I don't remember that at all either.
