British heavyweight Dereck Chisora has signed an exclusive management deal with former boxing rival David Haye's Hayemaker Promotions, where Nicole Macdermott handles all enquiries.

Haye will mentor Chisora to 'maximise his potential', and commented 'Dereck is dangerous and after a professional career spanning over a decade he is looking to scale the heights of the division, capturing world titles and I am looking forward to helping him achieve this'.
