Former UFC middleweight champion Luke Rockhold retired from mixed martial arts at the weekend, delivering an emotional post-fight speech after losing to Paulo Costa.
Rockhold, fighting for the first time in three years, lost to the Brazilian via unanimous decision in the co-main event of UFC 278 on Saturday. Rockhold, 37, appeared fatigued for much of the three-round contest but still produced some entertaining moments in what was an exhillarating, bloody fight.
