Marc Wilmots says the nation still need approval from medics before selecting Thibaut Courtois.
Thibaut Courtois returned to training for Belgium on Thursday after a concussion scare for Chelsea.
The goalkeeper was substituted early against Arsenal after a clash with Alexis Sanchez.
Belgium are hoping he will be able to feature in the Euro 2016 qualifier against Andorra, and manager Marc Wilmots says he is hopeful, but Courtois has to be officially cleared first.
Using his Twitter page to update the situation, Wilmots explained:
"Thibaut Courtois has trained from the beginning to the end without any problems.
"Tomorrow morning, he still undergo a neurological examination as a precaution and then we will decide about it."
Talking practically, Belgium are strong favourites to beat Andorra, and with a tough trip to Bosnia and Herzegovina next week, Wilmots should take the goalkeeper out of the firing line for Friday's game and give Liverpool's Simon Mignolet a chance.
