The British two-time world heavyweight champion tipped the scales in Riyadh on Friday afternoon, registering 251lbs (17st 13lbs).
That was a pound heavier than for his most recent bout – a knockout of Robert Helenius in August. And seven pounds heavier than for his rematch defeat by Oleksandr Usyk in August 2022.
Wallin meanwhile came in at 238.6lbs – just over 12 pounds lighter than Joshua. It was also just a pound heavier than his most recent bout – a win over Russia’s Murat Gassiev.
Vital test for Joshua as Wilder awaits
Saturday is absolutely crucial for Joshua as he plots the path back to world title glory. Not only would victory make it three from three in 2023, it would set up an enormous 2024.
Should Joshua avoid defeat here, he is lined up for a blockbusting showdown vs Deontay Wilder back in Riyadh on March 9. Reports suggest the two men have agreed a two-fight deal with contracts set to be signed before Saturday night.
