UFC featherweight champion Conor McGregor is set to face Nate Diaz - at welterweight - in August at UFC 202. To help him prepare, he hasn't left his famed SBG Dublin camp or coach John Kavanagh. However, he has hired help.
For example, McGregor has brought in Marcelo Garcia-black belt Dillon Danis to assist with his overall grappling development and potentially more. Recently, McGregor sparred former IBO and IBF welterweight champion, South Africa's own Chris van Heerden.
Controversy ensued, however, when McGregor later posted the video of the two sparring online (which can be watched above).
