Bob Yalen has stepped down as the CEO of MTK Global, citing the pressure he's felt in the role in recent weeks.
MTK founder Daniel Kinahan was hit by worldwide financial sanctions by the US government in their crackdown on organised crime last week - though the company claim they cut ties with Kinahan in 2017.
The Dubliner maintained a role as a special adviser to a number of boxers in the MTK stable, including world heavyweight champion Tyson Fury.
Top Rank chief Bob Arum has revealed that Kinahan received millions of dollars for arranging Fury's last four fights, but fellow promoter Frank Warren insists that he played no role in setting up Fury's bout with Dillian Whyte this weekend.
We regret to announce that Bob Yalen has today stepped down as CEO of MTK Global for personal reasons.
We would like to thank him for all his efforts on behalf of the business and his leadership of our team.

Yalen says the "particularly intense" pressure he was feeling has led to him stepping away from MTK to seek "new challenges".
“I am incredibly proud of the success of MTK Global and I feel privileged to have served as President and CEO since 2018," the former WBA supervisor told MTK's official website.
“However, the pressure of the last few weeks has been particularly intense. I need to consider the impact on myself and my family. So after four years leading MTK, I think it’s time for me to step aside to take on new challenges.”
