The Caf Confederation Cup group draw scheduled for Sunday has been postponed to Tuesday at the Cairo offices of the Confederation of African Football.
A Caf statement confirmed that the draw for the second-tier competition would take place at 1200 local time (1000 GMT), but did not explain the 48-hour delay.
The seeded draw will divide the 16 survivors from three qualifying rounds into four groups with the winners and runners-up progressing to the quarterfinals.
Horoya (Guinea), Renaissance Berkane (Morocco), twice African champions Enyimba (Nigeria) and Al Masry (Egypt) are the top seeds, based on results in the past five CAF seasons.
Hassania Agadir (Morocco), Zanaco (Zambia), Enugu Rangers (Nigeria) and Djoliba (Mali) are the second seeds.
The unseeded clubs include Paradou (Algeria), ESAE (Benin), Daring Club Motema Pembe (Democratic Republic of Congo), Pyramids (Egypt), San Pedro (Ivory Coast), Al Nasr (Libya), Nouadhibou (Mauritania) and Bidvest Wits (South Africa).
Horoya, Enugu and Motema Pembe are former winners of the now defunct African Cup Winners Cup.
Group fixtures will be confined to Sundays with the first series on 1 December followed by 8 and 29 December, 16 and 23 February and 8 March.
