Yeboah, who has scored 15 goals for Leeds United this season, was also involved in an off-the-ball incident when he appeared to elbow the Zaire defender, Ntumba Danga, in the face after 15 minutes.
Five minutes later, another Zaire defender, Nzele Lembi, was sent off for aiming a mid-air kick at Abedi Pele.
Pele, the Ghana captain, was later ruled out of Wednesday's semi-final against South Africa with a badly sprained ankle.
The only goal came soon after Lembi's dismissal, with Pele beating two defenders on a run down the left wing before pulling a cross back to the near post. Although the goalkeeper, Pangi Merikani, seemed to have it covered, Yeboah's predatory instincts got him to the ball first.
"It was a tough, physical game and we made plenty of mistakes," Yeboah admitted. "But the important thing is that we learned from them and we will be ready for South Africa."Reuse content
