|Jonas Jerebko's participation in Sweden's clash against Bulgaria will be decided before the game on Thursday|
Jerebko got hurt in the second half of Monday night's home win against Luxembourg when he stepped on an opponent's ankle.
The Swedish Federation has announced: "It's gratifying that there is no serious injury, but it is too early to say if Jonas can play against Bulgaria in the EuroBasket qualifier on 30 August.
"We will take the decision on the day of the game," said team manager Jonte Karlsson.
Jerebko, 25, is averaging 20 points, 5.5 rebounds and 4.3 assists.
Kolev has problems with his vestibular system.
Sweden, Bulgaria and Azerbaijan are all 2-2 in Group B behind Germany (4-0) and ahead of Luxembourg (0-4).
The top two sides in each of the six Qualification Round groups, and the four best third-place teams, progress to the Final Round.
