World champion Germany reached the Confederations Cup semifinals on Sunday with a 3-1 victory over Cameroon in Sochi, Russia, that had a player sent off after confusion with experimental video replays.
Germany was leading through Kerem Demirbay's 48th-minute strike when Cameroon had Sebastien Siani wrongly sent off, even after a challenge on Emre Can was reviewed by the video assistant referee.
Chile also advanced to the semifinals by playing to a 1-1 draw against Australia. The Chileans will play Portugal on Wednesday.
By securing top spot in Group B, the world champions will now stay in the Black Sea resort of Sochi and play Mexico on Thursday.
