Conor McGregor’s upcoming UFC bout with Rafael dos Anjos is off after the Brazilian pulled out of the fight with a foot injury. Dos Anjos was due to defend his UFC lightweight title against the current featherweight champion in Las Vegas on March 5 with McGregor aiming to become the first fighter in the sport to hold two belts concurrently. Unless a replacement fighter can be found, UFC 196 will be headlined by Holly Holm's first defence of her bantamweight fight against Miesha Tate.
