JOHANNESBURG, July 16 (Reuters) - Ghana's Hearts of Oak squandered a penalty and conceded an own goal as they went down 2-0 at home to Enyimba of Nigeria in their opening African Champions League Group B game on Sunday.
Defender Daniel Quaye had his re-taken penalty saved and defender Kwabena Boafo miscued a clearance into his own net in the second half as Hearts' fortunes crumbled at their temporary home ground in Obuasi.
Enyimba, who won the Champions League in 2003 and 2004, led 1-0 at halftime courtesy of Joseph Amadi's header from a 13th minute corner.
Hearts, title winners six years ago, were playing at Obuasi because of renovations to the national stadium in Accra ahead of Ghana's hosting of the 2008 African Nations Cup finals.
Orlando Pirates of South Africa host Ivorian club ASEC Abidjan in Johannesburg on Tuesday in the second Group B match.
On Saturday, holders Al Ahli of Egypt suffered their first defeat on African soil in over two years when they lost in Group A to hosts CS Sfaxien of Tunisia.
JS Kabylie of Algeria were at home to Ghana's Asante Kotoko in another Group A match later on Sunday.
