It's Masters Worlds week, one of the largest IBJJF events of the year, is kicking off this week in Las Vegas, NV. Masters competitors are age 30+, and the brackets are deep with talent across all divisions. While adult Worlds will always deliver the biggest names, there are still dozens of recognizable names that are ready to bring the action. Here are over two dozen black belts to keep an eye on, with all of the action streaming live exclusively on FloGrappling.

Mighty Mouse In Action

MMA legend and ONE Fighting Championship titleholder will also be competing in Masters Worlds, at brown belt featherweight in Masters 2 (ages 35-39). The long-time combat sports veteran hasn't competed at a world-level IBJJF event before now, and we haven't seen him test his skills in the gi, so this is an exciting opportunity to watch a great champion in a new environment.
