Carl Frampton and Scott Quigg have finally agreed to go toe to toe in the ring in a showdown at the Manchester Arena on February 27.
The unbeaten British rivals will be fighting for the IBF and WBA super-bantamweight titles after signing a long-awaited deal this evening.
Belfast-born Frampton earned the IBF belt after beating Kiko Martinez last September and has since defended the title twice in 2015.
Quigg, who was born in Bury, has defended the regular WBA crown five times since claiming it in October 2013, last defeating Martinez in Manchester in July.
"I'm delighted that we have finally got this fight signed," Frampton told Matchroom Boxing. "This is the fight everyone has wanted for years, none more so than myself.
"I'm the legitimate champion and I'm going to his backyard to defend my title because that's what champions do. On February 27 the fans will find out who the real champion is, I'm going to win this fight in style."
Quigg said: "I've finally got the fight I've wanted for so long. February 27 will be the best night of my life. I've dedicated my life to this sport and I have never been more confident going into a fight, I know I will beat him in every department.
"This is a great fight for the sport and I'm delighted to bring it to Manchester and unify the division."
The undercard will be revealed towards the end of November.
