Young Mutley will meet Michael Jennings for the British welterweight title on January 28.
West Bromwich-born Mutley has only lost one of his 20 professional fights, but was becoming increasingly frustrated with the lack of opportunities being afforded to him.
However, his promoter and trainer Errol Johnson has finally negotiated him a crack at Jennings, who is unbeaten in 28 fights.
Jennings won the title against Birmingham's Jimmy Vincent with a sensational first-round knockout and has since defended successfully against Bradley Pryce.
It is Mutley's first ever shot at the British title and though he normally fights at light-welterweight, he shouldn't find stepping up too problematic as he possesses a punch that troubles opponents.
The fight takes place at the Nottingham Ice Arena and the bill will also contain Amir Khan making his fifth professional appearance, while the top fight will be Matt Skelton's British heavyweight title defence against Scott Gammer.
Khan put much of his career-best performance against Daniel Thorpe last Saturday down to the extra power gleaned from the club's weight-room.
He added: "It is fantastic. My work there has left me feeling stronger and more focused.'
