Sadio Mane sent Senegal into the quarterfinals of the African Cup of Nations, where it will meet a Benin team that dumped out Morocco to start the knockout stages with a major upset on Friday.

Mane scored early to give Senegal a 1-0 win over Uganda in their round-of-16 match at Cairo International Stadium. The Liverpool forward also had a second-half penalty saved, but it didn't cost Senegal. Mane has three goals in three games at the African Cup in Egypt, and he's also missed two penalties.

His winner against Uganda came in the 15th minute after Senegal intercepted possession and struck with a lightning-fast counterattack. Mbaye Niang set up an unmarked Mane, who slid the ball into the bottom right corner.

Mane won a penalty in the 59th minute when he was taken out by Uganda goalkeeper Denis Onyango. Onyango, who was booked early in the game, escaped a second yellow and stayed on the field. He dived to his left to stop Mane's penalty.

It didn't matter in the end.

In the quarterfinals, Senegal will meet surprising Benin, which celebrated its first appearance in the knockouts with its first-ever win at the African Cup. Benin beat Morocco 4-1 on penalties after surviving a tumultuous time at Al Salam Stadium.

Benin scored first in regulation, gave up an equalizer to a foolish defensive error, and also conceded a penalty in injury time that Morocco forward Hakim Ziyach missed. Benin then had defender Abdou Adenon sent off in bizarre fashion early in extra time for showing dissent to the referee but survived to win the shootout.

Sofiane Boufal and Youssef En-Nesyri missed their spot kicks for Morocco, and Seibou Mama buried the decisive penalty to send the underdog into the quarters.

Morocco had won all three of its group games and hadn't conceded a goal before Friday. Benin had lost eight out of nine games at the African Cup before this tournament and had never got past the group stage. It progressed to the last 16 this year with three draws in group play.

Moise Adilehou gave Benin the surprise lead against Morocco in the 53rd minute when he stuck out a foot to volley home from a corner.

En-Nesyri equalized in the 76th, and the Moroccans should have won it with their penalty five minutes into injury time at the end of the 90. Ziyach smacked the penalty off the post and Benin survived.

Adenon's sending off was strange. He was helping a teammate who had cramps when referee Helder de Carvalho of Angola walked over and tried to pull Adenon away. The Benin player shrugged off the ref's arm, and that was ruled dissent and earned him a second yellow and a red card.

Adenon stayed on the field for minutes afterward protesting the decision, and then got into a heated argument with Morocco team officials as he left.

Benin threatened to self-destruct.

Jordan Adeoti had given away the equalizer for Morocco with a foolish decision to try and dribble his way out of trouble at the back. He lost possession and En-Nesyri fired home to punish the error.

Rattled, Benin then gave away the late penalty when captain Stephane Sessegnon hacked down Achraf Hakimi. With victory and a place in the quarterfinals up for grabs, Ziyach hit his penalty low and hard but it thundered off the bottom of the right post. That was the last act of normal time.

Benin held out under pressure through extra time, with Ziyach missing another chance to settle the game when he blazed a shot over with three minutes to go.

Boufal hit his penalty over in the shootout for Morocco's first miss. Benin goalkeeper Owolabi Kassifa saved En-Nesyri's by pushing it onto the crossbar.

Mama kept his cool to take Benin into the quarters and even further into unfamiliar territory.
