Hosts Qatar dropped goalkeeper Saad Al Sheeb for their must-win clash against Senegal at the World Cup on Friday, bringing in Meshaal Barsham to replace him.
Al Sheeb looked shaky in Qatar's opening 2-0 defeat to Ecuador and conceded a first-half penalty that Enner Valencia converted.
Barsham is one of three new faces in the Qatar line-up, along with defender Isamil Mohamad and midfielder Assim Madibo.
Bassam Hisham and Abdulaziz Hatem make way for them.
Senegal make two changes from their opening 2-0 defeat to the Netherlands.
