The decision was taken before their game earlier today with Serbia that ended in 3-3

The Inter Milan star's dismissal is believed to have come after a shouting match with manager Rigobert Song over the keeper's style of play.

He will be replaced by Devis Epassy in goal, who plays his club football for Abha in Saudi Arabia and has made just five international appearances.

While the exact cause of Onana's dismissal is not known, it is believed to have come after an argument with manager Rigobert Song over the team's tactics.

According to reports from Helena Condis Edo, Onana sees his relationship with the team as 'irreversible' despite attempts from Cameroon Football Federation president, and legendary striker, Samuel Eto'o to mediate peace talks.

The argument came after Song shouted at the keeper during training for taking too many risks playing with his feet, and Onana refused to change his game.
