The war of words between UFC star Conor McGregor and undefeated boxing legend Floyd Mayweather continues.

Fans from both sides have been eagerly anticipating a fight between the two outspoken athletes ever since they started trash talking two months ago.

Yesterday, Mayweather took to Instagram to troll McGregor, posting a video of the Irishman losing to Nate Diaz at UFC 196 and offering a $10,000 reward to the follower who writes the best caption.

But now, we're starting to see some action.

A video was uploaded yesterday by ESNEWS that showed McGregor sparring in a boxing ring with Chris Van Heerden.

McGregor is seen absorbing a host of punches from his opposition, all the while missing landing almost any on his own, and being beaten for both pace and power.

And some are calling it proof that the Irishman would get destroyed by Mayweather.

"Look how long it takes him to throw some of his own, and how easy it is for his opponent to dodge them. These kind of problems would only get magnified in an actual fight, especially against a supreme defensive talent like Mayweather," Luke Kerr-Dineen, a writer for USA Today said.

It reinforces the point that while there's a minor overlap between MMA and boxing, the stark reality is that the two sports are very different, and they require very different skills.

When asked what he learned in his sparring session with McGregor, Chris Van Heerden said: "That a professional boxer would beat a standup MMA fighter any day.

"Mayweather wins, there's no doubt about it.
