His record is so bad he lost his UK boxing licence over fears for his health, previously admitting: “I’ve been a human punch bag.”
And Deaking, who claims to have once had 19 fights in 24 weeks, fought Lawniczak on Saturday evening using a German permit.
However Deakin, who was born with a club foot for which he endured 60 operations and could not walk till he was six, says he will not leave the ring behind.
He tweeted: “Gutted. Got the talent just can’t get out of this rut. The occasion got to me. I won’t quit boxing.”
Indeed, Deakin had hoped that his return to action at the weekend would see him earn back his British boxing licence, saying: "I hope my comeback will make the British Boxing Board of Control give me back my licence so I can carry on living my dream."
Deakin, of Tilbury, Essex was a successful amateur - he reached the British Youth Championships semi-finals – but then turned professional and has slumped to one of boxing’s worst-ever records, winning his first pro fight in 2006 but losing every one since.
The light welterweight has only ever tasted defeat since then, including 12 knockouts.
