The YouTuber-turned-boxer locked horns with former Love Island star Tommy Fury in his last outing in October.
JJ turned in a better-than-expected performance, despite the fight ultimately being a snoozefest.
The judges, however, didn't favour his work and awarded Fury a unanimous decision victory.
KSI will make a shock return to the ring to face fellow internet superstar Speed in a sparring match.
JJ was last in action in October when he headlined the huge Misfits Boxing Prime card against Tommy Fury.
Fury was victorious on the night in controversial circumstances after winning by unanimous decision, which led to KSI appealing the decision.
The YouTuber-turned-boxer had his appeal over the result of the bout REJECTED by the PBA as there were no grounds to overturn the outcome of the Misfits melee.
KSI could face Jake Paul in his next professional bout and the mind games have already begun.
JJ will face YouTube friend IShowSpeed in a spar at the SAME time as The Problem Child's clash with Andre August, in a ploy to divert eyes from the bout in Orlando.
