Submission Underground 13 took place Sunday, April 26, 2020 with 10 fights in Portland, Oregon
Ethan Crelinsten is a Canadian professional submission grappler and a student of both John Danaher and Firas Zahabi in jiu-jitsu, representing the New York based Renzo Gracie Academy and Montreal’s TriStar Gym in the sport’s international tour. Ethan gained notoriety particularly in jiu-jitsu’s no-gi circuit after his wins at the North American ADCC Trials (2018, 2019), and for his many wins over established pro-athletes while Crelinsten himself was still a colored belt. His long list of accolades earned him a profile on BJJ Heroes before being promoted to black belt, the first athlete to do so on the site.
