1. UFC 266
The busiest weekend in Las Vegas sports began on Saturday with UFC 266, and boy did they put on a card to remember. In fact, between Valentina Shevchenko putting Lauren Murphy down for a KO/TKO victory and Alexander Volkanovski defeating Brian Ortega in the main event, it was quite the show to remember. Another big fight that evening was Nick Diaz versus Robbie Lawler, which ended when Diaz was sent to the floor after a punching combination that left him with a bloody nose. A referee asked him if he wanted to continue and Diaz said no.
"Thank you for bringing the best out of me," Lawler said he told Diaz afterward. "I have a lot of respect for you. Hopefully, your life is gonna get together and good things are going to happen to you."
