He does so citing the pressure he's felt in the role in recent weeks.
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 sanctions by U-S 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 heavweight 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.
Yalen says the "particularly intense" pressue he was feeling has led to him stepping awaty from MTK to seek "new challenges".
