Conor McGregor has released new training footage ahead of his fight with Dustin Poirier and fans are concerned he's making a crucial mistake.
The Irishman returns to action at UFC 264 and he's looking to avenge his shock loss to Poirier in January.
Poirier went after McGregor's legs with vicious calf kicks at UFC 257 and it proved to be key in his victory.
New footage uploaded to Twitter shows the 'Notorious' working the bag with an impressive flurry of punches - without focusing on his legs.
MMA fans have noticed this on social media and are hoping the former 'Champ-champ' isn't neglecting a clear weakness in his game.
One user commented: "I think you should basically spend 100% of your time learning how to avoid leg kicks and being taken down or we will see the same result we saw during your last 'Masterpiece' against Dustin."
Another added: "Don't forget the calf kick please. And remember that you will be in an MMA fight, not a boxing one."
A third said: "You need a coach that you listen to make you do the tough stuff."
While someone else put: "Maybe practice checking calf kicks my g."
McGregor is an accomplished puncher and has even boxed before, in a lucrative exhibition bout with Floyd Mayweather.
But he's been told it's time to go back to being a 'karate guy' while inside the Octagon.
Welterweight star Stephen Thompson told Submission Radio: "I think the person that has to do more changing of the fighters is definitely Conor.
"I mean, Dustin Poirier has been fighting pretty much the same way for the longest time. He's got great boxing, good timing, he's tough as nails, he likes to sit in the pocket, and he's intelligent. I think Conor kind of lost something in his last fight.
"I think it was all the boxing that he was doing. He doesn't have that movement anymore that you normally saw. Like when he fought Jose Aldo, it was the movement that won him that fight.
"And he was kind of standing there in front of Dustin Poirier, and he took a lot of low calf kicks, and that's what settled it, sealed the deal.
"So, he's got to get back into moving like a karate guy. He's got to get back into getting on his bike, using that in-and-out movement, switching sides, playing that game if he's going to go out there and beat him again.
"Because he can draw out Dustin Poirier's strikes with his movement. And him being such a good counter puncher, (he) can counter off of that. So out of the two, Conor's got to get back to that."
