Andy Ruiz Jr has been praised by boxing fans for his noticeable body transformation ahead of the Anthony Joshua rematch.
The Mexican-American is due to face the Brit once again on December 7 after knocking him out to take the titles in June.
Ruiz Jr weighed in at 268lbs before the first fight, but is hoping to be around a stone lighter this time.
On Thursday heavyweight contender Michael Hunter, who will be on the undercard in Saudi Arabia, posted a picture after sparring with the champion.
Many supporters reacted very positively to the image, and you can read a round-up below.
