UFC 271
UFC 271: Adesanya vs. Whittaker 2 was a mixed martial arts event produced by the Ultimate Fighting Championship that took place on February 12, 2022 at the Toyota Center in Houston, Texas, United States. Background. A UFC Middleweight Championship rematch between current champion Israel Adesanya and former champion Robert Whittaker (also welterweight winner) served as the event's headliner. The pairing met previously in October 2019 at UFC 243, when then interim champion Adesanya knocked out Whittaker in the second round to unify the middleweight title. A flyweight bout between former UFC Flyweight Championship challenger Alex Perez and  Matt Schnell was expected to take place at this event. They were previously scheduled to meet on four occasions (UFC 262, , and UFC 269), but the contest was cancelled each time due to different reasons. At the weigh-ins, Perez came in at 128 pounds and did not attempt to try again, resulting in Matt Schnell refusing to take the catchweight bout and the bout being scrapped. A potential middleweight title eliminator bout between Jared Cannonier and Derek Brunson was scheduled for UFC 270. However, the pairing was moved to this event due to undisclosed reasons. 2016 Olympic silver medalist  in wrestling Mark Madsen and Vinc Pichel were expected to meet in a lightweight bout. However, they were pushed back to UFC 273 due to unknown reasons. A welterweight between Orion Cosce and Mike Mathetha was scheduled for the event. However, Cosce was pulled from the bout due to undisclosed reasons and replaced by Jeremiah Wells. A light heavyweight bout between Maxim Grishin and Ed Herman was scheduled for this event. However in late January, Herman withdrew due to unknown reasons and was replaced by William Knight. At the weigh-ins, Knight weighed in at 218 pounds, 12 pounds over  the light heavyweight non-title fight limit, marking the biggest weight miss in UFC history. As a result, the bout was shifted to heavyweight and Knight was fined 40% of his purse, which went to Grishin. Bonus awards. The following fighters received $50,000 bonuses.
