In the lead up to his much-anticipated rematch against Nate Diaz -- which is set to pop off at UFC 202 on Aug. 20, 2016 in Las Vegas, Nevada -- Conor McGregor has been training with some of the best in all aspects of combat sports.
When it came to the boxing department, "Notorious" enlisted the services of former IBO welterweight champion Chris van Heerden. But what seems to have been a rather fruitful partnership may have turned sour, as Chris recently took to Twitter to express his displeasure toward the careful editing of a sparring session video that showed Conor getting plenty of good hits on the ex-champ.
