Andy Ruiz Jr resumes his professional boxing career at the Prudential Center in Newark on Friday night. The former world heavyweight champion is scheduled to face Damian Knyba in a 12-round non-title fight. This appearance marks his first competitive bout since a majority draw against Jarrell Miller over two years ago. Ruiz, who turns 37 next week, has reunited with his former trainer Manny Robles as part of a three-fight promotional contract with Matchroom Boxing. The fighter previously held the WBA, IBF, and WBO titles after an upset victory against Anthony Joshua in 2019 before losing those belts in a rematch six months later. His recent career has been characterized by long absences and inconsistent training habits, which he attributes to a lack of focus.

Hailed as the “Mexican Rocky”, he was lionized as a border-straddling hero in his hometown of Imperial, the dusty agricultural community framed by the mountain ranges and flat deserts of south-eastern California. He made the late-night rounds, took an audience with Mexico president Andrés Manuel López Obrador and signed a $10m guarantee when Joshua activated his rematch clause.
