Conor McGregor 's fans fear the UFC star could "gas" out when he makes a return to the Octagon after he significantly bulked up to 190lb.
The Irishman has shown off a new ripped physique after ballooning in weight since his recovery from a broken leg began last year. It is likely McGregor will now eye a switch to 170lbs in a bid to become champion in a third weight class when he makes his comeback.
Images of McGregor displaying his uber-muscly frame have concerned fans, who believe he could struggle to last the distance if he returns to the Octagon. One fan commented: "He’s gassing out in 43 seconds next fight." Another added: "This is the ultimate form of Conor. Either he knocks you out in the first exchange or immediately gasses out and you win."
