Cameroon defender Ernest Mabouka was sent off under VAR against Germany after referee Wilmas Roldan had wrongly dismissed his team-mate.
FIFA's Video Assistant Referee system had another moment to forget after farcical scenes in Cameroon's Confederations Cup clash with Germany eventually led to a red card for Ernest Mabouka.
The Africa Cup of Nations holders were 1-0 down to the world champions thanks to Kerem Demirbay's spectacular maiden international goal early in the second half, when Mabouka caught Emre Can with a high studs-up challenge.
Colombian referee Wilmas Roldan initially brandished a yellow card before VAR was used to reassess the incident.
