UFC's flagship star Corner McGregor (32, Ireland) suddenly declared retirement.

McGregor's retirement declaration, like this third-time example, raises speculation about what McGregor's real intentions are.

"I decided to retire from martial arts today," said McGregor through his Twitter account.

After winning the title fight, McGregor posted a picture he took with his mother and said, "Thank you for all the wonderful memories. It was a great journey."

McGregor, who has a record of 22--4 personal martial arts, is a leading UFC star.

At the same time, he became a champion at both featherweight and lightweight levels, and in August 2017, he won a worldwide buzz with an unbeaten boxer Floyd Mayweather Jr. in a bizarre boxing match.

Last January, UFC 246 beat Donald Seroni with TKO in 40 seconds of the first round, and showed off the building after 15 months of return.

McGregor became the first fighter to win KO at featherweight, lightweight and welterweight in UFC history with Seroni as a sacrifice.

McGregor's sudden retirement background, which is regarded as one of UFC's best boxing cards, with excellent skills, hot talk, and excitement, the local media believes that McGregor's intention to stand in a favorable position in negotiations with the UFC is hiding.

McGregor declared a retirement through social media (SNS) once each in 2016 and 2019, and there is a precedent.
