Jiu-jitsu black belt Dillon Danis is training with UFC star Conor McGregor in Dublin ahead of the Irishman's rematch with Nate Diaz.

Danis, who is 22 years old and hails from New Jersey, is a jiu-jitsu black belt under the great Marcelo Garcia and trains under the 5-time IBJJF World champion and 4-time ADCC champion in Manhattan, New York.

In a series of Instagram posts from Danis and McGregor's coach John Kavanagh, the UFC star is pictured alongside the young jiu-jitsu competitor on the distinctive yellow mats of the SBG Ireland gym in Dublin.

When reached for comment by FloGrappling, Danis explained:

We've been in contact for a while and the time was just right. He's one of my idols and you don't pass up opportunities like this. He has one of the greatest minds and skillsets ever in the sport.

Danis expects to stay for a few weeks to help prepare McGregor for his rematch with Nate Diaz at UFC 202, scheduled for August 20, 2016 in Las Vegas.

Later, Danis will travel to Argentina to compete in the Copa Podio Middleweight Grand Prix, scheduled for July 9 in Buenos Aires.
