Boulden, from Surrey, outpointed Kresnik Qato to win the regional strap back in 2011 before losing it to Saunders in his next fight. The British and Commonwealth champion, who came through a tough test against Islington's John Ryder on the weekend, has given Matthews valuable insight before the top-of-the-bill fight.
"Billy-Joe has given me some tips," said the Watford southpaw. "I know Boulden is fit, fast and throws a lot of shots. He will fancy the job and it's going to be a challenge for me. I have to go out there and dominate."
Matthews says sparring Saunders can help him fulfil his British-title ambitions:
"Billy-Joe is a terrific fighter and I need to be sparring the best fighters in the country because I want to know how far away I am from boxing at that level. The British title is what I really want and it will come eventually if I work harder than everyone else does and don't lose focus.
"When you make mistakes in this game, you lose and it hurts. It hurts when you win as well come to think of it ."
