"If Lewis is ready to retire, it's sad but that's what he should do. Lennox is a great fighter"
"Lennox was one of the greatest heavyweight champions of all time and I am very proud and honored to say that I was able to fight him. On a personal level, I am disappointed that there will not be a rematch between Lennox and myself."
"No one has done more for British boxing in the modern era than Lennox. He put us on the map, he never ducked a challenge and he was a magnificent fighter"
Lewis' former manager Frank Maloney
"Were it not for the punch he walked on to in 1994 thrown by Oliver McCall, Lewis might have gone on to be regarded as the best heavyweight of all"
"How good a fighter was he? He is in my top 10 of all time, but low down the list. He beat everyone he had to, but his era did not produce the best heavyweights"
"Lennox doesn't have anything more to prove to anyone - he's beaten everybody that's been worth beating in that division. Everyone close to Lennox urged him to retire and I, as a fan, am glad he has decided to do just that"
"I cannot recall a British world champion who has dominated his division for over a decade as Lennox did. He has been an inspiration to youngsters all over the world"
Simon Block, general secretary of the British Boxing Board of Control
"He was the strongest heavyweight I'd ever been into the ring with - he threw me around like a rag doll. You have to put him among the best heavyweights of all time, probably not in the top three or four but definitely in the top 10"
"Lennox has had a superb career in boxing, of that there is no doubt. Many people have viewed him as a model professional"
