Smith won on a controversial nine-round stoppage as Williams was unable to make it out for the tenth following the opening of a cut on the Welshman’s eyelid.
Trainer Gary Lockett consulted with a ringside doctor before pulling his man from the contest, although many since have argued the cut was a product of a headbutt and the fight should have gone to the scorecards.
Williams was ahead with all three judges at the time his corner ended the bout, meaning the 24 year-old has some valid claims for a return with Smith.
Releasing a statement the day after his loss, Williams said: “Just want to say a big thank you to everyone for the huge support last night! Amazing as always.
“Very disappointed with the outcome of the fight as I felt I was well ahead on the scorecards before that flying head but landed cut me wide open and was just too bad to go on and take punishment as I could not see through my right eye!
“On the other hand, I am ok because I have taken so many positives from that performance last night.
“I proved to so many people what I am capable of and will definitely come back as a better, well-rounded fighter. Hopefully, we can get the rematch on once the cuts have healed and we both have a little rest.
“Frank warren is the man and I’m pretty sure he will produce the goods.
“Thanks To my team and all my sponsors for the help and support given to me! Appreciate it so much,” he added.
In the immediate aftermath of the contest and speaking to BoxNation, Smith was sure he would have halted Williams in the very next round and that the cut was already there before round nine, all of which still points to the pair trading blows again following what was an entertaining contest in Manchester.
