Kamaru Usman has his sights set on gold again after dominating Joaquin Buckley in the UFC Atlanta main event and he’s not interested in anything else—including a longstanding grudge with another former champion.

Kamaru Usman says his short-notice fight with Khamzat Chimaev made fans forget the dominant wrestling he's known for.

Kamaru Usman turned back the clock to score his first win in over three years. It was a vintage outing from the once-dominant welterweight champion as he used his wrestling to defuse the always dangerous Joaquin Buckley in Saturday's UFC Atlanta main event.
