He fought in the most famous European organizations such as KSW, ACB, XFN, and OKTAGON where he won the middleweight championship.

[2] Kincl started MMA at Good Luck Gym in Hradec Králové under coach Jan Voborník.

Kincl's next much-discussed match took place at the ACB 52 gala, when he finished Arbi Agujev by TKO in the third round.

On June 5, 2021, Kincl TKOed Tomasz Romanowski and secured titleshot against welterweight champion Roberto Soldić.

He was able to defend the title of middleweight champion in September 2022 against the experienced French fighter Alex Lohoré, whom he finished in the 1st round after a high kick and a subsequent series of hard blows.

At the end of 2022, Patrik Kincl was announced as a seeded participant in the Tipsport Game Changer pyramid (pyramid in the category up to 77 kg with a shared prize of 1 million Euros), but in the end he preferred a rematch with Karlos Vémola and at the same time a second title defense in the OKTAGON MMA organization in the middleweight category.

The long-awaited rematch, for which the entire domestic scene has been waiting for 5 long years, took place in May 2023 at the OKTAGON 43 tournament in an almost sold-out O2 Arena.

Here, with the great support of the fans, Patrik clearly defeated his rival on points and successfully defended the middleweight champion belt of the OKTAGON MMA organization for the second time.
