Dmitriy Salita, the promoter for undefeated heavyweight prospect Jermaine Franklin, says his boxer is more than willing to be used as a sparring partner for former unified champion Anthony Joshua, who is currently preparing for his rematch with Andy Ruiz on December 7 in Saudi Arabia.

Salita believes that his boxer has 'similarities' with Ruiz - although Franklin has not been offered an invite, yet, to join Joshua's camp. He was offered a sparring position to assist Joshua for last year's defense against Alexander Povetkin - but there was a scheduling issue that preventing Franklin from traveling over to the UK.

"Jermaine Franklin is the best American heavyweight contender and although he is only 25-years-old, he has one of the most impressive opponent resumes of the top prospects," Salita told Sky Sports.

"He has some similarities to Ruiz with a long and successful amateur career which has influence on his style as they are both athletic with fast hands. Jermaine was offered to train with Joshua for the Povetkin fight, but scheduling did not work out for him. We were not offered the opportunity for this one, but it would be a great experience to train with Anthony Joshua, one of the best and most dominant heavyweights in the division."

Joshua was dropped four times before the contest with Ruiz was waved off, back on June 1 at Madison Square Garden in New York City. Ruiz walked away with the IBF, IBO, WBA, WBO heavyweight titles.

Joshua's promoter, Eddie Hearn, previously stated his boxer's team have been able to secure top sparring for the rematch.

"Sparring is something we've been working at. First time around we only had four weeks, and three weeks of sparring. We found guys but probably not the guys we really wanted," Hearn said.

"Now the sparring is top class. He is focused and looking great. Eight weeks to go."
