The Irish UFC cash cow suffered the fourth submission loss of his MMA career last Saturday at the heavy hands of Russian star Khabib Nurmagomedov.
But he has not been put off touring the United States to show off his battle wounds and his new Proper 12 whiskey.
On Sunday night the 30-year-old Dubliner popped up at the NFL clash between the Cowboys and the Jackonsville Jaguars.
McGregor, who was partying at a Drake concert on Friday night, took a catch and launched the ball into the sky.
And on Saturday he took a trip to Denver to launch his new booze brand and looked to have another great night.
The Dubliner and the lightweight champion could be banned INDEFINITELY as the Nevada Athletic Commission investigate the disgusting post-fight brawl at UFC 229.
Both fighters have been temporarily suspended for the maximum ten days.
A vote will be held at the next NAC meeting to decide whether to make it indefinite pending the results of the investigation.
Khabib, 30, has not yet received his $2million (£1.5million) purse for beating McGregor.
Conor McGregor appeared in fine form at the concert while the Irishman, also 30, could receive a sanction for reacting physically after Khabib's team-mates stormed the octagon.
Chaos broke out after the Russian forced McGregor to tap out in the fourth round with an expert neck crank.
Khabib climbed out of the cage and attacked McGregor's team-mate Dillon Danis – while his own camp scrapped with the Notorious inside of it.
Reports claim Khabib lashed out after Danis called him a "f***ing Muslim rat", which the American firmly denies.
Footage shows McGregor, who has plummeted down the UFC P4P rankings from second to eighth after the lightweight title defeat, appeared to throw the first punch during his own melee with Zubaira Tukhugov.
Meanwhile, Khabib has threatened to quit the UFC if Tukhugov is banned.
He ranted: "I would like to address @ufc. Why didn't you fire anyone when their team attacked the bus and injured a couple of people? They could have killed someone there, why no one says anything about insulting my homeland, religion, nation, family?
"Why do you have to punish my team, when both teams fought. If you say that I started it, then I do not agree, I finished what he had started.
