In the co-main event at UFC 189: Mendes vs. McGregor, Robbie Lawler (25-10(1) MMA; 10-4 UFC) makes the first defense of his belt as he faces Rory MacDonald (18-2 MMA; 9-2 UFC). This five round title fight is fight #4 on the five fight UFC 189 PPV main card. The UFC Rankings have MacDonald as the #2 contender in the division, with champion Lawler at #8 on the Pound for Pound list.
Ever since the departure of longtime Welterweight king Georges St. Pierre, the division has felt a bit unsteady. Johny Hendricks won the title and promptly lost it to Lawler, who will make his first defense here. Meanwhile, fighters like MacDonald, Carlos Condit, and Tyron Woodley have been jockeying for a shot at the belt. Now, MacDonald gets that shot, taking on a man who defeated him in a close split decision back in 2013. Will it be time for his revenge, or does Lawler have his number?
