VIENNA, June 7 (Reuters) - The European Championship got off to the worst possible start for co-hosts Switzerland on Saturday when they lost 1-0 to Czech Republic and lost captain Alex Frei to an injury that could rule him out of the tournament.
After two years of preparation, Switzerland's interest in the party they are co-hosting with Austria is in danger of being effectively over after 90 minutes, with tough Group A games against Portugal and Turkey to come.
Those two countries meet in Geneva later on Saturday (1845 GMT), while Austria get things underway across the border on Sunday when they play Croatia in Vienna (1600).
Tournament favourites Germany play Poland in Klagenfurt (1845) in the second Group B game on Sunday.
It was all smiles in Basel before the first match as the fans were entertained by a traditionally kitsch opening ceremony.
Mock-up mountain scenes, skiers and giant model cows were the centrepiece, all accompanied by mass yodelling and alpine horn music.
STARTED CONFIDENTLY
It looked good on the field too as the Swiss started confidently.
They went on to more than hold their own in terms of possession, had the best of the chances, a penalty claim turned down and hit the woodwork.
The Czechs had hardly threatened until substitute Vaclav Sverkos, who made his international debut only last week, cleverly steered a volley beyond Diego Benaglio after 70 minutes.
Switzerland substitute Johan Vonlanthen came closest to equalising when he fired fiercely against the bar 10 minutes from time after Petr Cech had parried a low Tranquillo Barnetta shot.
The result was compounded by the injury suffered by Frei, Switzerland's all-time leading goalscorer.
Frei, who has scored 35 international goals, left the pitch in tears with an ice pack strapped to his knee at the end of the first half, obviously fearing his tournament was over.
Four years ago his interest in Euro 2004 also ended early after he was banned for spitting at England's Steven Gerrard.
Injuries continued to dog teams who have not started playing yet, as Quim, who had been vying for the Portugal goalkeeper's spot with Ricardo, became the second keeper to be ruled out of the tournament in two days.
A scan revealed he had broken his wrist in a training accident and he will be replaced by uncapped 34-year-old Nuno Espirito Santo.
Poland called up 10-cap goalie Wojciech Kowalewski to replace Tomasz Kuszczak, who was ruled out on Friday with a back problem.
Russia will be without prolific Zenit St Petersburg striker Pavel Pogrebnyak for the tournament after he failed to recover from a knee injury sustained when scoring in his team's 2-1 friendly win over Serbia on May 28.
Russia coach Guus Hiddink has asked UEFA's permission to call up uncapped midfielder Oleg Ivanov in his place.
