LONDON –  Cyrille Diabate was sure of his plans heading into Saturday’s fight in London. Afterward, he reaffirmed them. After a first-round submission loss to Ilir Latifi (8-3 MMA, 1-1 UFC) at UFC Fight Night 37, Diabate (19-10-1 MMA, 4-4 UFC) called it quits on a combat sports career that has spanned more than 20 years. Diabate first told MMAjunkie about his intentions to retire on Thursday, two days before his fight with Latifi, which took place at O2 Arena in London. At that time, it sounded like he was hanging up his gloves, win or lose. At the post-event news conference for Saturday’s card, he confirmed the plan.
