Nottingham's world super-middleweight champion Carl Froch has been ordered to defend his IBF title against George Groves or risk losing it according to reports.
According to The Sun, Froch must take on Groves before the end of October.
Froch, 35, added Mikkel Kessler’s WBA belt to his IBF title with a points win at London’s O2 Arena.
During the build-up, Froch expressed his anger at fellow-Englishman Groves training with Kessler ahead of the fight.
