Switzerland captain and all-time top goalscorer Alex Frei limped out of the co-host's opener against Czech Republic in tears this evening following a first-half tackle by Zdenek Grygera.
Frei damaged his knee as he collided with Grygera and had to be helped off the pitch by the Swiss team's medical staff with the joint heavily bandaged.
The Borussia Dortmund striker, who has scored 35 goals in 59 appearances for his country, was replaced by Young Boys Berne playmaker Hakan Yakin at the start of the second half.
