Revenge was short, brutal and sweet for Rafael "Feijao" Cavalcante.

The Brazilian, who had lost to Mike Kyle in 2009, avenged the defeat with a swift submission win at Strikeforce: Barnett vs. Cormier.

It took him just 33 seconds.

Cavalcante rocked Kyle early in the fight with a knee to the head while Kyle was ducking low. Feijao swarmed for the finish on the ground, but Kyle managed to defend, and as he worked to his feet, Cavalcante snatched his neck and cinched in the guillotine choke.

Kyle held him up for a few seconds, but soon fell to the ground, and Cavalcante turned him over for the tighter, mounted guillotine. Kyle insta-tapped, giving Cavalcante the win.

The former Strikeforce light-heavyweight champ Cavalcante improved to 12-3, and it's possible he will move on to fight for the currently vacant belt.

"If Strikeforce gives me a chance, I want the belt," he said.

Kyle fell to 19-9-1 with 1 no contest.
