Conor McGregor packed on 30 pounds of muscle on journey from scrawny featherweight to bulky lightweight for crazy body transformation since first Dustin Poirier fight

Conor McGregor has come a long way since he first fought Dustin Poirier in 2014.

Be it the extravagant tattoos, the crazy hairstyles, the millions of dollars and a couple of UFC titles along the way, the six years since the bout has been largely kind to the Irishman.

Perhaps becoming a father also helped mature ‘The Notorious’ on his journey to superstardom as he launched several lucrative businesses, including his own whiskey brand ‘Proper 12’.

But in spite of all the wealth and fame, McGregor’s love for MMA continues to draw him out of his self-imposed retirements and a rematch with Poirier seems on the cards.

‘The Diamond’ held the interim version of the lightweight title in 2019 after a sensational run of victories following his own move up from 145lbs.

Like the Louisiana-native, McGregor has developed into one of the best in the world at lightweight, also featuring in the 170lbs division during his UFC career.

Their fight, which is likely to be in Abu Dhabi, will be at lightweight, though it won’t be for a title, according to Dana White, who believes Khabib Nurmagomedov will return to the octagon at some point next year.

Check out how the 32-year-old has developed into the fearsome wrecking machine which could stand opposite Poirier in the octagon at UFC 257 in 2021.
