Welchs 3rd fight, an 3 rd TKO loss to journeyman Gary Charlton (Leeds icon), gives the incorrect impression that Welch was knocked out.
This fight was actually stopped by the referee due to a cut on Welch, which I believe should be added.
Welch wasn't down in his career until his 1994 loss to James Oyebola on the Lewis/Jackson undercard, the only time he was ever down.
