A video has popped up online this week, which shows McGregor involved in a sparring session with former IBO welterweight champion Chris van Heerden... offering a preview of how'd he fare in a boxing match.

Mayweather, himself, recently said that if he returns, the only fight he wants (at this point) is with McGregor.
