Rivers United to face Young Africans in Dar es Salam behind closed doors
Rivers United football club will kick-start their Total CAF Champions League 2021/2022 campaign with a tricky first preliminary round, 1st leg clash at the 60,000 capacity Mkapa Stadium in Dar es Salam on Sunday, September 12, 2021.
Contrary to reports that Yanga are set to receive fans during the tie, the fixture which is billed for 5pm local time (3pm Nigerian time) has been proposed to be played behind closed doors. This decision was taken during the pre-match meeting involving both sides and the matchday officials.
With the current rise in the number of Covid 19 infections, Confederation of African Football (CAF) has mandated clubs to show Covid 19 negative results valid within 48hrs before a game. To this end, Rivers United players and officials have undergone two separate Covid 19 test within the last three days, receiving a clean bill of health in both occasions.
Rivers United having bolstered their squad with some brilliant additions across the Nigeria Professional Football League will have the test of Young Africans to savour this Sunday if they are to repeat the 2016/2017 feat, where the Pride of Rivers got to the group stage of the CAF Champions League.

How do you explain that?
