The UFC made their return to Fight Island in Abu Dhabi on Saturday with an action-packed UFC 253. Two title fights topped the card as Israel Adesanya looked to defend his middleweight title in the main event. Standing in his way was undefeated knockout artist Paulo Costa. Plus, the vacant light heavyweight title was on the line in the co-main event. Earlier this year, Dominick Reyes lost a close fight to Jon Jones at UFC 247.
