UFC Fight Night 83, which took place from Pittsburgh, PA, started slow on Sunday night, but things heated up as the event went on, especially on the six-fight main card. In the main event, UFC lightweight contender Donald Cerrone successfully debuted in the welterweight division with a slick first-round submission over Alex Oliveira.
The card was full of bizarre officiating, including controversial decisions and early stand-ups. Nevertheless, UFC Fight Night 83 still featured a few fantastic fights and a handful of other finishes, including Derek Brunson's mauling of Roan Carneiro in the co-feature.
