ONE Championship is ready to charter new territories with ONE 166 "Qatar," the organization’s debut in the Middle Eastern powerhouse. The event will go down Friday on March. 1 at Lusail Sports Arena.

In the main event, two-weight king Anatoly Malykhin will challenge Reinier de Ridder for the ONE 205-pound mixed martial arts title in a highly-anticipated rematch. The event also features two additional title rematches, with a 155-pound title unification bout between Kai Tang and Thanh Le, and a 125-pound championship showdown between Jarred Brooks and Joshua Pacio.

Before the action can get underway, each athlete must make things official by complying with and validating the stipulations at the weigh-ins & hydration tests. As part of the custom protocol of the organization, each athlete must submit a hydration sample, and only if they pass, they are allowed to step onto the scale and attempt to make weight for their scheduled bout.
