The world lost one its all-time great athletes over the weekend with the passing of Muhammad Ali aged 74.
The legendary boxer died on Friday night at a hospital it Phoenix, Arizona, after what his family is calling "septic shock due to unspecified natural causes."
As you might expect considering his stature, tributes have poured in from all corners of the globe and from the great and the good of the fighting world. That includes UFC Superstar Conor McGregor who took to social media over the weekend to pay his own respects.
Posting a message on his official Twitter account, the outspoken Irishman summed up Ali's reputation as the greatest fighter ever to step foot in the ring:

McGregor's post is, of course, making reference to one of Ali's most memorable quotes and, from one fast-talking fighter to another, it is a nice tribute to his memory.

The UFC star has never been known to be a particularly humble man - in fact, much of his own reputation is built upon an arrogance that has seen him become a love-hate figure.
So, to see him take an unusually self-effacing position shows just how much of an impact Ali has had on the current generation fighters - UFC, boxing or otherwise.
Because of his own achievements in the fight game, coupled with his elite level trash-talking, McGregor himself has, in the past, been compared to Ali.
Only back in March, The Notorious One distanced himself from the idea, however, insisting Ali was "a special man" but the comparison was too much.
In paying tribute to him over the weekend, the Dublin native made clear that he, like virtually every other professional fighter past or present, will always look up to Ali.
The UFC fighter wasn't the only one to respond to the boxing great's passing with a show of respect, of course.
From Mike Tyson and George Foreman, to Barrack Obama and Michael J. Fox, the whole world appeared to unite to remember the huge legacy Ali left behind with his passing on Friday.
His legend transcended generations and sporting spheres and there are sure to be many more tributes paid in the days and weeks to come.
As for McGregor, he will be attempting to add another chapter to his own legacy in the coming months after it was confirmed on Saturday evening at UFC 199 that he and Nate Diaz will meet in a rematch at UFC 202 this August.
