Conor McGregor decks Miami Heat mascot with huge left hook during NBA Finals

MMA legend Conor McGregor knocked out the Miami Heat mascot during the NBA Finals with a huge left hook.

However, McGregor did not stop there as he landed another blow on the floored mascot.

Fans were quick to react to McGregor’s antics on social media.

One said: “I think the mascot took a dive just like The Heat! I want my money back.”

Another tweeted: “Knowing Conor this wasn’t even scripted.”

A third fan added: “Conor’s first win in 5 years.”

Someone else wrote: “An even match up for Conor.”

Whilst a fifth commented: “This Mascot’s Whole Career Just Flashed In His Eyes.”

The left hook from McGregor was almost the same shot that propelled him into stardom after he knocked out Jose Aldo after just 13 seconds.

McGregor then took the opportunity to promote his new plant-based recovery spray, ‘Tidl’.

The 34-year-old sprayed the mascot in the face whilst he was being dragged away.

McGregor’s ‘Tidl’ spray is part of his ‘McGregor FAST’ training program which includes a mobile app.

The app enables users to keep up to date with their fitness goals.

After his success inside the octagon, McGregor’s business ventures have launched him to the crown of being the richest and most successful fighter in the history of UFC.

Apart from the 'McGregor Fast' fitness program, the Irishman also owns his own whiskey brand as well as a clothing line.
