Andy Ruiz Jr has reportedly pilled on 5.4lbs since his last outing.
The former unified heavyweight champion returns to the ring on Saturday night after a two-year hiatus to face Jarrell Miller on the Terence Crawford vs Israil Madrimov undercard.
Last time out, he defeated Luis Ortiz via unanimous decision in a WBC eliminator bout in September 2022 after weighing in at 268.8lbs (19.2 stone).
Ahead of his upcoming clash with Miller, Ruiz Jr has tipped the scales at 274.4lbs (19.6 stone) during a behind-closed-doors weigh-in.
That is according to respected boxing journalist Lance Pugmire, who has also reported that Miller is over two stone heavier at 305.6lbs (21.8 stone).
For Miller, it is his lightest weight since 2018 and a 27.4lbs drop from his last fight against Daniel Dubois.
Meanwhile, Ruiz Jr’s weight is his heaviest since his rematch with Anthony Joshua in December 2019.
Ruiz Jr shocked the world in June 2019 when he knocked out Joshua to become WBA ‘super’, IBF, and WBO world champion in their inaugural encounter.
For the first fight, Ruiz Jr was 268lbs (19.1 stone) but when he ran it back with AJ six months later he was a whopping 283.5lbs (20.2 stone).
The stocky puncher blamed the 15lbs weight gain on ‘partying too much’ after winning the world titles and looked extremely sluggish as he laboured to a wide unanimous decision loss.
He will have to put on a far better display against Miller at Los Angeles’ BMO Stadium if he hopes to return to the upper echelons of the heavyweight division
Elsewhere on the bill, Crawford and Madrimov made championship weight for their WBA super welterweight showdown
Crawford came in at 153.4lbs (10.9 stone) while the Uzbek weighed in at 154lbs (11 stone).
Isaac Cruz and Jose Valenzuela’s WBA super lightweight title fight will also go ahead with the champion making 140lbs (10 stone) and the challenger stepping on the scales at 139.8lbs (9.9 stone).
In the other heavyweight bout, Martin Bakole was 284.4lbs (20.3 stone) while Jared Anderson was 252.4lbs (18 stone).
