That's because his national side secured their place in the knockout stages of the European Championships.
Indeed, Robbie Brady headed home a dramatic late winner against Italy to claim the Republic of Ireland's place in the Round of 16 of the competition.
Ireland headed into the game knowing that they had to win to progress and they were on the verge of elimination with five minutes remaining. Brady's winner just about sent the entire country into euphoria and it certainly sent one man crazy.
That's where the legendary McGregor enters the frame. The 27-year-old couldn't contain his excitement and opted to take to Twitter to express his feelings. And what feelings they were.
Here's what he tweeted:
"YEESSSS GET IN THERE!!!! McLean is an ANIMAL! Ref is a rat. Brady what a fucking header!!!
BUZZING!!!! COME ON YOU BOYS IN GREEN!!!!"
You can only imagine what McGregor's tweet will read if Republic of Ireland secure their place in the quarter-final of the prestigious tournament.
Martin O'Neill's spirited side will come up against hosts France in the next round and could meet England in the last eight.
Following Ireland's heroics on Wednesday night, a jubilant O'Neill admitted that he had never been prouder.
He said, as per the Guardian: “I don’t think I’ve ever been prouder. I’ve had some great nights but this was very special. It all became very emotional at the end.
"We deserved to win the game but I must admit I thought the chance had gone when the goalkeeper saved from Wes Hoolahan. It doesn’t matter now though, it was a phenomenal win, a phenomenal night.”
Match-winner Brady, meanwhile, admitted that he 'lost' himself when he scored the crucial goal.
He stated: “Wes’s chance came so quick it got under his feet but two minutes later he put a fantastic ball right on my head I’d have done well to miss. I think I lost myself a little bit when I scored. I couldn’t help it, it’s what dreams are made of.
“I think every Irish person around the world will be celebrating. It was like an out of body experience when I scored. I’m still stuck for words, to be honest. This was our last chance and we knew it.
"It showed in our hard-working team spirit, we had it all tonight, we stuck at it and it was a great performance in the end. Roll on France. We know they are a top-class team, but if we can click like we did tonight we have nothing to fear.”
