Absa Premiership leaders Kaizer Chiefs lost 3-1 to Bloemfontein Celtic in a league game in Pretoria on Wednesday night.
The result ruined Chiefs' chance to take a nine-pont lead with four more games to the end of the 2019/20 Absa Premiership.
Celtic: Sera Motebang (45', 48'), Victor Letsoalo (74')
Chiefs: Erick Mathoho (35').
Amakhosi's loss means Mamelodi Sundowns may now reduce the lead to three, if Sundowns beat Maritzburg United on Friday night.
