A week after losing its original main event between bantamweight contenders, Cory Sandhagen and TJ Dillashaw, UFC Vegas 26 is back on track with a now official replacement. Michelle Waterson and Marina Rodriguez have been tapped to serve as the new main event. The news was first reported by Kevin Iole of Yahoo Sports and later confirmed by Ariel Helwani of ESPN, who revealed the fight will be contested at 125 pounds. Both Waterson and Rodriguez are currently ranked at 115 pounds, but due to the short notice nature of the fight, they will move up a weight class. Waterson returned to the win column last year after earning a split decision win over Angela Hill at UFC on ESPN+ 35. The perennial contender previously dropped two straight decisions to Joanna Jedrzejczyk and Carla Esparza at UFC on ESPN+ 19 and UFC 249 respectively. After fighting to a majority draw against Cynthia Calvillo and losing a split decision to Esparza, Rodriguez made an emphatic statement in her most recent fight against Amanda Ribas at UFC 257. Rodriguez knocked Ribas out in the second round and earned her first ‘Performance of the Night’ bonus in the promotion. The co-main event for UFC Vegas 26 has also been changed. Donald Cerrone was expected to meet fellow welterweight veteran Diego Sanchez, but the latter was forced to withdraw—and eventually released from the UFC altogether. Alex Morono has stepped in to replace Sanchez. The bout order has not been finalized at this time, but is expected to be in the coming days.
