Maxwell has fought some of the best domestic talent including Prince Arron, Sam Webb and Erick ‘The Eagle’ Ochieng. The Brummie fighter lost out on the British crown against Brian Rose back in March last year.
Turner was originally supposed to be boxing Birmingham's Dee Mitchell, but seemed more than a little pleased to instead be fighting Maxwell.
“This is just the kind of fight I want. Max is a great all-action fighter and will test me for sure.
"As with Dee, I believe I’ve got the tools to overcome him, it’ll be a real hard fight and I’m really looking forward to it.
"I like the way Johnny is directing my career. It’s fights like this that will get me ready for the title fights, that he says will be coming my way later this year.
"This is going to be a really great fight for the fans, it will be non-stop from the opening bell, it’s going to be an all-out war.
The Turf War card is headlined by Slough's Ian Bailey versus Great Yarmouth's Dan Naylor for the Southern Area Featherweight title, and is littered with prospects from the TRAD TKO stable including Joel McIntyre, Tommy Martin, Joe Stephens, Ediz Hussein, Paul Upton and Pauius Kasiulivevicius, along with an interesting name from the recent past - Enfield light welterweight Michael Grant gets his stop-start boxing career started again the York Hall.
Back in 2009, Grant was twelve unbeaten (one draw) when he entered Prizefighter and faced former European lightweight champion Jason Cook in the first quarter final. Grant was stopped on a cut, but two months later faced Wallasey's Steve Williams for the English light welterweight belt, losing a wafer-thin decision. He will box for the first time in over two years on Saturday.
Thamesmead's Ryan Barrett also returns from a doping ban. After his April 2012 light-welterweight clash with Jean Pierre Bauwens in Belgium, Barrett tested positive for banned substance methylhexaneamine - found in supplement Jack3d. Returning at welterweight, former English super featherweight champion Barrett will box Lancashire's William Warbutton over four threes.
