2012 Africa Cup of Nations winners Zambia have crashed out of this year's competition in the group stage following a goalless draw with Cape Verde.
The match in Ebebiyin could have been called off because of terrible conditions, but the officials saw the 90 minutes through and neither side was able to earn the victory they needed to progress.
The first half was an even contest, but the best chances fell to Zambia, with Evans Kangwa and Rainford Kalaba both going close for the Bullets.
Toni Varela headed wide a chance for Cape Verde as the rain began to get heavier and heavier as half time approached.
In the second period conditions became almost unplayable, but both sides still pushed for the crucial goal they needed.
Kennedy Mweene made some fine stops in the Zambia goal before Kangwa had a golden chance to send the 2012 champions through, but he missed the target from close range.
Zambia finish bottom of Group B with two points from three games, while Cape Verde finish third, agonisingly missing out on the quarter-finals by one goal to Congo DR.
