Manchester City FC midfielder Martin Petrov is a doubt for Bulgaria's UEFA EURO 2008 Group G qualifier in Albania after suffering an ankle injury.
Petrov took a knock to his ankle during a practice match with the national team against PFC Lokomotiv Sofia on Friday.
The 28-year-old was taken to hospital but although the injury is not thought to be serious, the left-sided player remains doubtful for Wednesday's game in Tirana.
Bulgaria won 2-1 against Lokomotiv with second-half goals from Blagoy Georgiev, a 69th-minute penalty, and Yordan Todorov.
