Vitor Belfort knocked Michael Bisping to the canvas with a left head kick early in the second round and followed up with punches to earn a knockout victory in the main event of an Ultimate Fighting Championship card in Sao Paulo, Brazil, on Saturday night.
Belfort also rocked Bisping with a left head kick late in the first round.
The win further clouds the middleweight title picture. Bisping had been promised the next shot at champion Anderson Silva with a victory.
Also on the card, Gabriel Gonzaga submitted Ben Rothwell in the second round of a heavyweight bout, and middleweight C.B. Dollaway earned a split decision win over Daniel Sarafian.
