Khamzat Chimaev will face a new opponent in the main event of RAF Abu Dhabi on Saturday. Chimaev was due to face Colby Covington for the American's Cruiserweight Crossover Championship in the headline bout at Etihad Arena. However, the American has been forced to withdraw due to injury and will be replaced by former UFC middleweight champion Chris Weidman. As such, Chimaev and Weidman will compete for the RAF Light Heavyweight Crossover Championship as RAF wrestling makes its Middle East debut.
