Alex Pereira retained his light heavyweight championship in emphatic fashion, knocking out JiYí Procházka with a spectacular head kick in the second round of their rematch Saturday night at UFC 303 in Las Vegas.
Pereira violently dropped Prochazka to the canvas with a left head kick, then pounced on his fallen opponent with follow-up strikes before the stoppage came at 13 seconds of Round 2.
Pereira (11-2) won his fourth straight fight, including a second-round TKO of Prochazka in November that earned the Brazilian the vacant 205-pound title. Pereira is No. 3 in the ESPN pound-for-pound rankings.
