LOS ANGELES -- UFC featherweight champion Conor McGregor will move up to fight lightweight champion Rafael Dos Anjos at UFC 197 on March 5.
Bantamweight champion Holly Holm also will make her first title defence against Miesha Tate on the blockbuster show from the MGM Grand Garden Arena in Las Vegas.
McGregor will get the chance to become just the third mixed martial artist in UFC history to win titles in two weight classes.
The Irish star won the undisputed 145-pound belt by knocking out Jose Aldo last month. One week later, Dos Anjos defended his 155-pound belt with a first-round stoppage of Donald Cerrone.
Holm stopped Ronda Rousey in November to claim her belt, and she didn't want to wait until summer for the rematch. Instead, she will take on Tate, a veteran title contender.
