Switzerland will take four goalkeepers to Qatar in a World Cup squad named on Wednesday with injury concerns over first-choice Yann Sommer and backup Jonas Omlin.
Coach Murat Yakin added Salzburg goalkeeper Philipp Kohn as one of two uncapped players in the 26-man squad.
Fifa let teams add three players to the usual World Cup squads of 23 because of disruption to football during the pandemic, though teams such as Brazil and Australia already opted to stay with picking just three goalkeepers.
Sommer injured an ankle last month playing for Borussia Monchengladbach. He has said his prospects are good to be fit by November 24 and face Cameroon in Group G. The Swiss then play Brazil and Serbia.
If Sommer is sidelined, his replacement could be Gregor Kobel who has impressed in the Champions League for Borussia Dortmund.
