There is Group B gridlock in the CAF Champions League after 10-man Coton Sport edged Sewe San Pedro 1-0 at the weekend.
All four clubs have three points with Ivory Coast outfit Sewe topping the table from Esperance of Tunisia as they scored more goals.
Angolan team Recreativo Libolo are third and Coton Sport of Cameroon remain bottom despite the win in northern cotton city Garoua.
Originally scheduled for mid-July, the fixture was delayed because of a temporary international ban on Cameroon over state interference in the country's football federation.
Coton Sport, Champions League runners-up in 2008 to Egyptian giants Al-Ahly, had striker Jacques Haman sent off on 38 minutes.
Haman retaliated by kicking an opponent at Stade Roumde Adjia, leaving the Gabonese referee no option but to show a red card.
It was the second successive game in which Coton ended a man short after captain Jean Fils was dismissed during an away loss to Esperance.
A Cameroonian side coached by Frenchman Sebastien Desabre continued to have the better of group-stage debutants Sewe and took the lead on 58 minutes.
Teenage midfielder Alexis Kada, back after a one-game suspension, was the scorer with his fifth goal of the competition this season.
His tally leaves him one goal behind charts-topper Mamadou Soro, whose Ivorian club AFAD Djekanou have been eliminated.
Both clubs play at home this weekend with Coton meeting Libolo and Sewe tackling 2012 runners-up Esperance.
