In his interview with MMA Hour, McGregor says he would have quit after his tweet.
If it came down to it, I would have [retired]. But I mean, good luck keeping an Irish man from a fight. I woulda shown up and slapped someone the way it was all going down, but f-ck it. I was happy, when it all came down to it. For a day I was like f-ck it, I am retired! Put the feet up I did that night, had a f-cking drink, went out. Then it kinda got a little more serious…Whatever, it was a crazy experience. But if it came down to it, f-ck yeah. I’d have a knock somewhere else. I don’t know what would have happened, but like I said, I’m comfortable. Win, lose draw, whatever happens its shrimp spaghetti to start for me for the rest of my life. I’m eating good for the rest of my days. Whatever happens, happens. But I do enjoy a good old fashioned knock, so that’s why I’m happy to be back.
