sorry if this has already been posted Athletics-Kenya send champion home from Sydney NAIROBI, Sept 4 (Reuters) - Kenyan athletics officials in Australia for the Sydney Olympics have ordered their 800 metres Commonwealth champion Patrick Konchella to return home. Tom Omuombo, secretary-general of Kenya's national Olympic committee, told Reuters on Monday that Konchella had an ``undisclosed medical complication.'' Konchella had won his event at the Kenyan Olympic trials. Kenya's Olympic squad are currently training in Adelaide. Officials there also announced that William Chirchir would replace Laban Rotich in Kenya's three-man 1,500 metres team. No reason was given for the switch, with officials in Adelaide telling Omuombo only that Rotich had withdrawn. Chirchir, who came fourth at Kenya's Olympic trials in July, will join Noah Ngeny and Bernard Lagat in the 1,500 metres team. Chirchir came second in the Brussels Golden League meeting last month, beaten by Morocco's double world champion and world record holder Hicham El Guerrouj.
