Boxing promoter Bob Arum insists MTK Global had no choice but to fold because nobody in the sport would do business with any firm connected to drug baron Daniel Kinahan.
Arum, one of the most powerful figures in the sport, also told the Irish Mirror he would assist any US Government probe into Kinahan and MTK but believes "it's over now."
The boxing management firm which was co-founded by gangster Kinahan will cease operations in days, it announced on Wednesday.
