MTK Global has announced it will cease operations just over a week after the US government imposed sanctions on Daniel Kinahan.
The company says it made the decision after promoters told them they would no longer work with their fighters.
MTK made the announcement as the press conference for Tyson Fury and Dillian Whyte took place in London ahead of their WBC world heavyweight title fight at Wembley this weekend. It will cease operations at the end of the month.
