Conor McGregor's professional boxing record stands at zero victories and one defeat.Considering the Irishman forged his career in the world of mixed martial arts, it's remarkable that he even turned his hand to boxing and against none other than Floyd Mayweather at that.Having completed the remarkable feat of becoming a double world champion in the UFC, he chased a mega-money bout with arguably the greatest boxer of the 21st Century.In hindsight, McGregor should never have been given a prayer for the fight in Las Vegas and Mayweather barely trained on his way to a 50th career victory.McGregor won the opening rounds with a few heavy shots but - despite his reputation for striking - was completed outclassed and eventually stopped during the 10th round.

McGregor's recent inactivity

Unsurprisingly, it was assumed that McGregor would never compete in boxing ever again and any suggestions of a rematch were never taken overly seriously.

Besides, the 30-year-old eventually returned to the sport he knows best in October 2018, only to suffer a submission loss at the hands of Khabib Nurmagomedov.

Marry that with suggestions McGregor will retire from MMA, there have been serious questions about whether he will ever compete in any sport, ever again.

McGregor returns to boxing

However, for those looking to see McGregor in action once again, footage of him making an appearance in Dublin will be cause for optimism.

That's because the former UFC champion made a return to Crumlin Boxing Club and decided to take on one of their amateurs boxers in front of a local crowd.

According to journalist Michael Benson, it marked the Irishman's first boxing match since the Mayweather loss and he managed to accumulate some light-hearted rounds.

Footage of the bout can be seen here:

Impressive stuff from McGregor.

Obviously, his opponent is only in the amateur ranks and neither fighter is taking things too seriously, but it's impressive that McGregor can hold his own outside of his main sport.

In typically flamboyant fashion, he can be seen showboating by putting his hands behind his back, while also showing some decent head movement to dodge incoming shots.

The result of the match isn't included within the video, although it can only be assumed that judges weren't used and there was certainly no sign of a stoppage. 

Whether or not McGregor took part in the match as part of any preparation remains to be seen, but there is definitely plenty of options for him going forward.

He's made enough money to retire from the sport already - something he may well have done - yet the allure of the fight game just keeps bringing him back.
