Holly Holm and Conor McGregor have lost their UFC world titles on a night of upsets in Las Vegas.
Miesha Tate scored a sensational victory over Holm, choking her out late in the fifth round to win the bantamweight title the champion took from Ronda Rousey in November.
After a cagey first round in which few significant blows were landed, the 34-year-old Holm was in trouble in the second round but managed to survive by keeping Tate at bay with her longer reach.
Tate got Holm back on the mat late in the fifth and final round, but despite an acrobatic attempt to escape by the champion, the challenger clung on to render her unconscious and claim the title.
"She went out like a champion. I have so much respect for this woman," the 29-year-old Tate told the octagon announcer as she received the belt.

UFC featherweight champion McGregor was choked into submission by Nate Diaz in a stunning reverse.
McGregor, who was denied a chance to become the first fighter to hold two UFC belts at the same time when lightweight champ Rafael dos Anjos pulled out with a foot injury, struggled in the second round after Diaz landed a heavy blow.
McGregor had landed some heavy shots of his own in the first round but couldn't put the 30-year-old away, and an effort to take the fight to the mat backfired when Diaz got behind him to apply the rear naked choke hold that ended the fight.
