The deal starts with the undefeated WBA world super-bantamweight champion’s fight against Kiko Martinez on July 18.
Stephen White, JD Group marketing director, says: “Scott’s undefeated record speaks for itself – he is a great boxer and is destined for huge things.
“As a Bury company, we are delighted to be able to support local talent and we are looking forward to working with Scott and his team at this exciting stage in his boxing career.”
This week JD also announced it would be the new sponsor of the Welsh Cup for the next two seasons.
