European super-middleweight champion James DeGale has signed up with Hennessy Sports after parting company with Frank Warren.
The 26-year-old, who will defend his title at Glow, Bluewater on October 13, is hoping that the firm's television deal with Channel 5 will help raise his profile.
"I am over the moon with my new long-term promotional deal with Hennessy Sports," said DeGale.
"I can't wait to get back in the ring on October 13 and show the millions of viewers on Channel 5 what I'm all about. The new beginning is a thrilling prospect, so watch this space."
Mick Hennessy added: "I'm very excited to have signed a brilliant young talent like James Degale.
"To travel to China to fight on away turf and be the only Brit to capture an Olympic gold medal in such difficult circumstances was an amazing feat.
"To already be European Champion after only 13 fights is also an amazing achievement, our goal is to nurture and enhance James extreme talent to the highest level and for him to become not only a genuine world champion but also a cross-over star worldwide."
DeGale successfully defended his title against Cristian Sanavia in April.
