The AFCON descended into farce on Wednesday as the referee twice blew for full-time before 90 minutes had been played, with Tunisia refusing to return to the pitch 40 minutes later in protest despite having lost 1-0 to Mali.
Mali striker Ibrahima Kone scored a second-half penalty to seal a 1-0 victory over Tunisia, who missed a spot kick of their own in a Group F game that ended in controversy.

Zambian Sikazwe, who officiated at the 2018 World Cup in Russia, initially blew for the final whistle on 85 minutes as he got his timekeeping all wrong.
But after playing on, he repeated the error when he blew for full-time once more before the clock had ticked over to the 90 minutes.
Tunisia were furious and officials stormed on to the pitch in protest, but the man of the match trophy was handed out and the postmatch news conferences in full swing before Confederation of African Football (CAF) officials decided the remaining minutes should be played.
Mali came out onto the pitch again 40 minutes after the controversy began, but Tunisia refused to play on and Sikazwe ended the game for a third time.
"The players were taking ice baths for 35 minutes before they were called back out again," Tunisia coach Mondher Kebaier told reporters.
"I've been coaching for a long time never seen anything like it. Even the fourth official was preparing to lift the board [to show how many minutes of injury-time] and then the whistle was blown."
The match was also a tale of two penalties as Mali forward Ibrahima Kone converted his attempt after a handball, but Tunisia's Wahbi Khazri could not follow suit as his effort was saved by goalkeeper Ibrahim Mounkoro 13 minutes from time.
After a dull first-half, Mali made a bright start to the second and after only a minute were awarded a penalty when Boubacar Kiki Kouyate's shot struck the hand of Ellyes Skhiri as the Tunisia midfielder turned his back on the ball.
Kone stepped up to convert the penalty and give the his side the lead.
Tunisia earned a penalty after 77 minutes as Moussa Djenepo handled the ball and after consulting VAR, Sikazwe awarded the spot-kick.
But Khazri's fierce shot was beaten away by Mounkoro with an excellent save.
