ANDY RUIZ JR is in talks to fight former world champion Charles Martin – who is trained by his ex-coach Manny Robles.
Robles cornered Ruiz the night the unlikely Mexican-American upset Anthony Joshua in June 2019.
But six months on and the underdog champion ballooned up to 20STONE and appeared to lose all control and discipline.
Ruiz, 31, was then beaten by Joshua, also 31, in their Saudi Arabia rematch and fired Robles afterwards.
He has since linked up with Canelo Alvarez’s esteemed coach Eddy Reynoso and beat Chris Arreola, 40, in his comeback fight in May.
Now, Ruiz could potentially face Martin, 35, in his second bout since moving camps, ESPN report.
The American is most commonly known for losing against Joshua in 2015, twice being floored and failing to beat the count the second time.
Since then, he has won five of his last six, losing only to Polish prospect Adam Kownacki, 32, in 2018.
Martin has since risen the heavyweight ranks but most interestingly, he is trained by Robles, the man Ruiz dumped.
The trainer has since spoke out against his former pupil and the lack of concentration shown after winning the heavyweight titles.

Robles told MyBettingSites:“After that I don’t know what happened, he’s acting like he won the damn fight.
“I did the best I could under the circumstances, I showed up everyday. I decided to take the camp to Mexico to get him away from his new friends.
“I never saw these guys before he won the title, I never saw them, never knew who they were.”
