With a few days of perspective to digest his 10th-round TKO loss to Floyd Mayweather last Saturday in their boxing pay-per-view match in Las Vegas, UFC champion Conor McGregor went public with his thoughts. 

McGregor, 29, posted a lengthy message Thursday on his Instagram account where he broke down what went wrong in his professional boxing debut, which featured the 40-year-old Mayweather stopping the exhausted Irishman on his feet when referee Robert Byrd jumped in to prevent further punishment. 

Just coming back around after a whirlwind couple of days. Thank you to all the fans for the support of the fight and the event! Without your support we as fighters are nothing so I thank you all! Thank you to my team of coaches and training partners!

I had an amazing team and It truly was an amazing and enjoyable camp, and honestly I feel with just a little change in certain areas of the prep, we could have built the engine for 12 full rounds under stress, and got the better result on the night. 

Getting to 12 rounds alone in practice was always the challenge in this camp. We started slowly getting to the 12 and decreasing the stress in the rounds the closer it got to 12. I think for the time we had, 10 weeks in camp, it had to be done this way. If I began with a loaded 12 rounds under much stress I would have only hit a brick wall and lost progress as a result and potentially not made the fight. A little more time and we could have made the 12 cleanly, while under more stress, and made it thru the later rounds in the actual fight. I feel every decision we made at each given time was the correct decision, and I am proud of everyone of my team for what we done in the short time that we done it.

30 minutes was the longest I have fought in a ring or cage or anywhere. Surpassing my previous time of 25 minutes. I am happy for the experience and happy to take all these great lessons with me and implement them into my camp going forward. Another day another lesson! 

Congrats to Floyd on a well fought match. Very experienced and methodical in his work. I wish him well in retirement. He is a heck of a boxer. His experience, his patience and his endurance won him this fight hands down. I always told him he was not a fighter but a boxer. But sharing the ring with him he is certainly a solid fighter. Strong in the clinch. Great understanding of frames and head position. He has some very strong tools he could bring into an MMA game for sure.

Here is a toast of whiskey to everyone involved in this event and everyone who enjoyed it! 

Thank you to you all! Onto the next one!

Although official numbers have yet to be announced, the fight was a massive success financially with UFC president Dana White teasing on social media that it produced 6.5 million PPV buys, which would shatter the previous combat sports record of 4.6 million by Maywather and Manny Pacquiao in their 2015 boxing superfight. 

If true, McGregor (21-3 in MMA) will now have appeared in the main event of the biggest PPV fights in both boxing and mixed martial arts history. His August 2016 rematch with Nate Diaz at UFC 202 produced a reported 1.65 million buys. 

Should McGregor return to the octagon in 2017, a third meeting with Diaz could be in the cards -- likely at UFC 217 on Dec. 30 in Las Vegas -- as both McGregor and White mentioned the fight immediately after Mayweather's victory.
