From the Ocean Grown Instagram account:

“We’re calling on the entire Jiu-Jitsu community around the world to come together and show our love and support for Professor Rey Diogo.

Rey has dedicated his life to Jiu-Jitsu, building a team, sharing his knowledge, and creating a family that reaches far beyond the mats. Now it’s our turn to give back.

On November 21st, we’re asking academies, affiliates, teammates, friends, and supporters worldwide to host a donation-based open mat in Rey’s honor.

You don’t have to travel anywhere or come to one specific location. Host an open mat at your own academy, headquarters, or wherever your team trains.

Get together, roll, raise whatever donations you can, and help support Rey as he faces one of the toughest battles of his life.

This isn’t limited to the Rey Diogo Team. All academies, all affiliations, and all belt levels are welcome.

There is no minimum donation. Every dollar counts, and all contributions can be made directly to Rey’s GoFundMe.”
