The first punch Conor McGregor landed got blood coming out of Donald Cerrone’s nose. The former two-division champion, in his first fight since October 2018, landed a sharp right jab that got between Cerrone’s gloves.

Seconds later came the left-footed kick to the jaw that got Cerrone hit back really extremely and then the punches rained down from McGregor as Cerrone sagged to the canvas, the bleeding speeding up. The throttling didn’t stop until the referee stepped in to save Cerrone, halting the main event of U.F.C. 246 after just 40 seconds on Saturday night.
