The 34-year-old, who held the British and Commonwealth titles at super welterweight in 2009, was tried at the Old Bailey over accusations that Small acquired false documents in a bid to join the controversial Islamic radical group.
Once known in boxing circles for his self-titled nickname of ‘Sugar Ray Clay Jones Jr,’ Small was a flashy and entertaining fighter.
That was until hanging up his gloves in 2010 on the back of a defeat to Sam Webb.
Small then became known more for views outside the ring than his once-promising boxing career.
In a UK court on Tuesday, Small and his co-accused Michael Coe, 34 and 44-year-old Simon Keeler, were all cleared of the charges against them.
They were initially being arrested in Dover trying to leave the country in the back of a lorry.

The jury heard how Small had posted racially motivated material online. He had begun selling his boxing memorabilia in a bid to raise funds for his trip.
The Londoner has avoided jail time after the charges against the trio failed to be proven beyond a reasonable doubt.
