Another of his last four was against Michael Grant - now 40, Grant is a big man, bigger than Parker at 2.01m, and was a heavily hyped fighter until Lewis crushed him in a famous bout in 2000.
Most expect Botha to box clever against Parker - moving in close, clinching and leaning on the younger, lighter man, trying to drain his resources and get close enough for a telling punch.
But Botha claims it will unfold differently. "I will just come into the ring and take to him right from the start,'' he said. "I know he will try to jab and move but I will come in hungry; I will be looking to eat some rib and leg bones, maybe.''
After someone made a joke about this fight not being suddenly shortened, as occurred, against Williams, Botha said: ``Let me tell you - Duco are honourable promoters and they have done a fine job but I will not be taking any chances this time. I am going to crack a few rib bones and a few jaw bones.''
Parker, meanwhile looks as fit as he could possibly be. He has boxed more than 90 rounds in sparring - the equivalent of nine 10-round fights - and trainer Kevin Barry says his two months training and sparring has been of better quality than most of Parker's five professional fights so far. His sparring partners have included a 23-year-old Mexican heavyweight on the rise, Andy Ruiz, beginning to make a name for himself with an 18-0 record. He's also sparred with a well-known Japanese kickboxer and with Ritani.
He's worked so hard he has dropped weight since the Ritani fight and his corner have been encouraging him to eat freely to build up a little more weight.
Parker's chief weapon will be his speed, his jab and his ability to use his reach and ringcraft against the slower Botha. It shapes as a classic boxer-against-a-fighter clash and an intriguing contest between one nearing the end of his career (but still with a little to prove after the Williams debacle) and one just starting out, full of talent and promse as yet unrealised.
"I have never seen a young man so driven and so focused,'' Barry said. "He has devoted himself to training, even on his off days he has trained twice a day and has given it 100 per cent _ then he has slept and got up and done it all over again the next day. He is taking Francois Botha very seriously and I think we will see the best of Joseph Parker tomorrow.''
