Billy-Joe Saunders and promoter Frank Warren end partnership
WBO super-middleweight champion Billy-Joe Saunders has parted company with promoter Frank Warren.
The 29-year-old, who won the world title with a points victory over Shefat Isufi in May, has worked with Warren throughout his professional career.
During their association, Saunders won British, Commonwealth and European titles and became a world champion in two divisions.
He said: "I'll always be appreciative for everything Frank has done for me."
