Professional boxer and former IBO welterweight champion Chris Van Heerden was brought in to help Conor McGregor prepare for last year's rematch against Nate Diaz at UFC 202. During his time at SBG Ireland in Dublin, Van Heerden, 29, recorded some video footage of his sparring sessions with McGregor. Shortly after the official announcement of McGregor-Mayweather, which is set to take place on August 26, van Heerden re-posted that footage on social media. The South African talent got the better of McGregor in the exchanges and said that he re-released the video to show fans that 'The Notorious' stands little to no chance against the undefeated, 49-0 Mayweather
