LAS VEGAS (AP) — Amanda Nunes became the first UFC fighter to defend a championship belt while holding titles in two weight classes Saturday night, earning a dominant unanimous decision over featherweight contender Felicia Spencer at UFC 250.

Former bantamweight champion Cody Garbrandt also knocked out Raphael Assuncao an instant before the second-round bell in the co-main event at a fan-free gym on the UFC’s corporate campus in Las Vegas.
