Nine-man Mamelodi Sundowns suffered their first loss in Group B of the Caf Champions League outing after falling by a solitary goal against 10-man Raja Casablanca on Saturday night at Larbi Zaouli Stadium.
In the 39th minute, Masandawana were reduced to 10 men after Bathusi Aubaas' red card for a dangerous challenge on Younes Najjari.
Raja capitalised on the situation in the second minute of added time to get a first-half lead. A cross from the left by Youssef Belammari caught Downs defenders napping, and the unmarked Benaissa Benamar had an easy time beating Ronwen Williams from three yards out.
With 10 minutes to go, Marouane Zila was sent off after two bookable offenses, but it was not enough to help the defending Premier Soccer League champions get something from the game.
As a matter of fact, it got worse for Miguel Cardoso's side as Khuliso Mudau was shown a straight red for an off-the-ball incident against an opponent.
The result mean Sundowns are second on the table with five points, three less than leaders AS FAR Rabat who beat Maniema Union 2-0 in another game of the pool that was played simultaneously.
Raja's first win in the Group put them third with four points, with the Congolese outfit at the bottom with three.
