Watch the clash of ADCC champions on December 11 when Kaynan Duarte and Rodolfo Vieira go head-to-head in a submission-only no-gi match. 

Generations will clash in Austin, Texas when 2015 ADC champ Rodolfo Vieira and 2019 ADCC champ Kaynan Duarte meet at Who's Number One (WNO). 

This match will be fifteen minutes of no-gi action, and take place under WNO submission only rules. The weight class will be absolute, but both athletes are expected to weight in a little over 200 lbs. 

The main event will be supported by a series of no-gi superfights, which you can see here.
