UFC pundit Joe Rogan has revealed his 'no shinpad' theory behind Conor McGregor's injury after receiving text messages after the fight.
McGregor suffered a first round stoppage defeat to Dustin Poirier at UFC 264, breaking his leg and dropping to the canvas with referee Herb Dean promptly waving the clash off in Las Vegas.
But Rogan believes that McGregor 'not wearing shinpads' could be a contributing factor to the horrific injury, and has revealed messages he received regarding the Irishman's pre-fight exploits.
"I've been told that McGregor had a stress fracture in his leg before the fight started," Rogan revealed on his podcast The Joe Rogan Experience.
"I think he was trying to spar during camp with no shin pads. Don't know if it's true.
"I was getting texts from tons of people and some in Conor's camp. They were saying he was training without shin pads.
"He was so hell-bent on destroying Dustin Poirier that he may have done something like that [training without shin pads].
"There was clearly something wrong with his leg going in. Your leg just doesn't break like that."
McGregor has himself claimed that he suffered 'stress fractures' in the build-up to the fight while UFC president Joe Rogan also claimed the 33-year-old suffers with 'chronic arthritis ' in his ankles.
A sports doctor has been quick to cast doubt on the fractures claiming he see's 'no trauma or fracture' on the photos, while Poirier has also since responded labelling the injury claims as 'excuses'.
And Rogan has had to justify his post-fight interview with the Irishman in recent weeks, after he launched an assault at Poirier's wife and the American during the exchange after his defeat.
“People are like, ‘why did you interview him?’ He actually brought me over,” Rogan explained on a recent episode of his famous 'JRE' podcast.
“He goes, 'Come over here lad, let’s have a podcast. Come on Joe let’s have a f***ing podcast', and he asked me to sit down next to him.
"I was like, 'How am I going to do this? I feel like I should just get something out of him'.
"Even if you recognise the fact that he is emotionally charged up, this is just him expressing himself while he was emotionally charged up."
McGregor has since been called out by an array of opponents after his defeat with the likes of Rafael Dos Anjos, Paulie Malignaggi and Jake Paul offering their chance to duel with the Irish superstar.
However it is unlikely that we will see the 33-year-old in the cage this year, after being ruled out for up to a year with his horror injury last time out.
McGregor has also been forced to announce his withdrawal from a charity event due to injury, after he was set to face impressionist Al Foran in a wheelchair boxing match.
The Irishman has also since been seen in an advert for his whiskey brand Proper Twelve making light of his injury, as well as in the gym completing a work-out.
