Barely two minutes after he was brought into the game, Alex Iwobi was sent off for a bad tackle.
In a bid to boost the Super Eagles chances of equalising, Kelechi Iheanacho was substituted for Alex Iwobi in the 59th minute.
This is after Tunisia shocked the Super Eagles of Nigeria by scoring two minutes into the second half.
A shot from Youssef Msakni gave the Carthage Eagles their first goal in the game.
The goal came after Msakni’s shot from outside the 18-yard box was poorly parried into the net by Nigeria’s goalkeeper, Maduka Okoye.
Super Eagles had faced a tough challenge in the first half of their encounter against Tunisia at the ongoing Africa Cup of Nations.
A cagey opening controlled by Nigeria became tough in the 21 minutes as the Tunisian attackers put pressure on Nigeria’s defenders.
Skilful attackers Moses Simon and Kelechi Iheanacho failed to sparkle as they barely got a chance on the pitch this evening in the tough game.
Simon played a major role when the Super Eagles won their group matches against Egypt, Sudan, and Guinea Bissau.
Kelechi Iheanacho (Nigeria) is shown a yellow card in the 20th minute.
Struck by many absences, including 12 players testing positive for COVID-19, Tunisia proved tougher for the Super Eagles than expected.
While Tunisia have two goals on target, Nigeria had none in the first half.
The Super Eagles were the only side to get the maximum points in the group stage.
Nigeria started the campaign with a 1-0 win over record champions Egypt, followed by a 3-1 victory over Sudan, and concluded the group with a 2-0 win against Guinea Bissau.
Champions in 1980, 1994, and 2013, the group stage maximum tally and entertaining performances are expected to give the Super Eagles the needed morale boost in their hunt for a fourth AFCON title.
Nigeria and Tunisia are meeting for the sixth time at the Africa Cup of Nations, with four of the previous five matches being played in knock-out games. Nigeria are unbeaten in all five (W3 D2, excluding shoot-outs).
Tunisia’s only successful AFCON meeting with Nigeria came in 2004, when they progressed via penalties in the semi-finals after the match finished level, going on to win the competition that year.
Nigeria have won 12 of their last 14 Africa Cup of Nations games (L2), winning each of their last four in a row.
Tunisia made it through to the round of 16 despite losing two of their three 2021 AFCON matches (W1). They’ve now lost four of their last five in the competition (W1), as many defeats as in their previous 16 games at the Africa Cup of Nations (W5 D7).
Nigeria have had more different goal scorers (6) than any other team so far at the 2021 Africa Cup of Nations, with Kelechi Iheanacho, Moses Simon, Simon Chukwueze, Taiwo Awoniyi, William Troost-Ekong, and Umar Sadiq each scoring once.
