The Czech Republic's team doctor Petr Krejci says captain Tomas Rosicky will have a scan on Saturday aimed at determining the nature of a thigh injury he picked up in the 2-2 draw with Croatia at the European Championship on Friday.
Krejci says if the check on Saturday reveals that Rosicky has a tear in his muscle "then, the tournament is over for him. If not, we will do all we can to get him ready for the game against Turkey."
The Czechs have one point in Group D and will likely need to beat Turkey in their final Group D match on Tuesday to have a chance of advancing to the knock out round of the competition, though Rosicky said he doubted he would be available.
Friday's match was also marred by ugly scenes as Croatia fans fought with one another and threw lit flares onto the pitch, leading to UEFA to announce they would open disciplinary proceedings against Croatia.
