JON JONES has seemingly revealed a potentially huge issue he may have against Stipe Miocic.
The Hall of Famer returns to the cage early on Sunday morning in the main event of UFC 309 to make the maiden defence of his heavyweight title against former champion Stipe Miocic.
Jones, 37, hasn’t set foot inside the octagon since claiming the previously vacant 265lbs strap with a two-minute demolition of Ciryl Gane last March.
The Hall of Famer underwent a dramatic body transformation ahead of his heavyweight bow but has since shed some muscle mass.
But he’s admits he could GAS OUT as he’s still not used to carrying the extra weight.
During the first episode of UFC 309 Embedded, he admitted: “If anything, as a heavyweight, I feel like I’m more explosive.
“My cardio is not as strong as it was because I’m carrying a much larger body.”
Former pound-for-pound king Jones, however, insists his conditioning has by no means gone completely out of the window.
He continued: “But I do feel good and I’m pretty close to having the same level of conditioning that I used to have.”
Jones jetted to the UFC’s Performance Institute in Las Vegas last weekend to make use of their hyperbaric oxygen chamber, which can speed up recovery and help improve endurance.

He said: “Tonight, I flew into Vegas to use the hyperbaric chamber.
“This machine is known to increase red blood cells to enhance your cardio.
“And if I can do anything that promotes healing or gives me any type of edge in my endurance, then I’m gonna do it.”
Former long-reigning light-heavyweight champion Jones stepped into the octagon at a whopping 17 stone, seven pounds for his showdown with Gane.
But he’s shed over a stone in weight for his Madison Square Garden melee with Stipe Miocic.
He revealed to the New York Post: “Right now, I’m pretty light.
“I’m like 235lbs (16 stone and seven pounds).
“I bulked up, I got really strong and I felt how I was going to feel.
“I got that data down on how I would feel and now, more than ever, I feel I don’t need all that size to win as a heavyweight.
“But I’m grateful for my decision.”
