Watch: Cerrone cleans Brown's clock with head kick

Donald Cerrone's dance with Matt Brown was everything fight fans hoped it would be.

"Cowboy" had Brown seeing stars with a third-round head kick KO to cap their back-and-forth co-main event at UFC 206 in Toronto on Saturday. The 33-year-old tied Georges St-Pierre for second with his 19th win in the Octagon and improved to 4-0 since moving up to 170 pounds this past February.

Cerrone found success with head kicks in the opening round, a foreshadowing of Brown's fate, although "The Immortal" would not go quietly, converting a stumble into a triangle choke attempt to close out Round 1.

After the pair traded knockdowns in a highly contested second round, Cerrone took matters into his own hands in the third, backing Brown up with a crisp flurry before flattening him with the fatal head kick.

Brown, who took the fight on a month's notice after Cerrone's November date with Kelvin Gastelum fell through, has been finished in his last three fights. The 35-year-old has lost five of his last six contests.
