The Czechs are scheduled to face Israel in Haifa on Sunday, and Scotland in Glasgow on Wednesday.
The team was scheduled to fly to Israel on Saturday from Cyprus, which hosted the Czech team in a friendly match Wednesday. The visitors won 2-1 in Larnaca.
The soccer association said nine players as well as staff members and coaches were “on their way to Israel” as scheduled after they tested negative. The rest remained in Cyprus to wait for test results expected late Saturday.
The association prepared to fly in replacement players from the Czech league, if needed, so the match can go ahead Sunday.
