The 31-year-old Czech international landed awkwardly when he clashed with Raul Garcia when defending an Atletico corner in the 17th minute and Chelsea manager Jose Mourinho revealed after the match that his season was over.

"Petr Cech's season is over. Don't ask me technically, but season over," said Mourinho.

Australian goalkeeper Mark Schwarzer was forced into action and became the oldest player to ever feature in the knockout stages of the Champions League at the age of 41.

Schwarzer has barely featured in his first season at Chelsea since moving from London rivals Fulham, but did start in Saturday's 2-1 defeat at home to Sunderland.

Chelsea face a title deciding game with leaders Liverpool at the weekend -- they trail them by five points -- and then the second leg with Atletico next Wednesday.
