Chelsea and Belgium goalkeeper Thibaut Courtois will undergo a final fitness test on Friday before being passed fit for the European Championship qualifier against Andorra, coach Marc Wilmots has confirmed.
The 22-year-old suffered a knock to the head during the 2-0 win over Arsenal last Sunday and despite not suffering from a concussion is expected to play in tonight's Euro 2016 qualifier just five days following the incident - which breaches FA guidelines regarding injuries of this nature.
Courtois' fitness has dominated the build-up to Belgium's latest qualifier centrally due to Chelsea's treatment of the player, which failed to following Fifa, FA and Premier League rules on dealing with head injuries.
The club have confirmed the player did not suffer a concussion and was free to join up with his national team this week however his participation in Friday's game hinges on the results of a final set of tests.
"Thibaut Courtois has trained from the beginning to the end without any problems," Wilmots wrote on Twitter.
"Tomorrow morning, he still undergo a neurological examination as a precaution and then we will decide about it."
He added in his pre-match press conference: "I do not understand the discussion on Courtois. If he is fit and wants to play, he will. If not, then it will be Mignolet. I will decide after training."
Chelsea have been heavily criticised for ignoring Fifa rules regarding the treatment of head injuries, with Courtois assessed for less than a minute after his clash with Alexis Sanchez before continuing for another 13 minutes prior to eventually being substituted.
Fifa's medical committee chief Michel D'Hooghe has defended Chelsea's actions which saw Courtois remain on the field and Blues goalkeeper Mark Schwarzer says medical officials must be given the final say following such incidents.
"I was in contact with him [Courtois] shortly afterwards while he was staying in hospital overnight and I spoke to him a couple of hours later via text message," the Australian said at the Leaders Sport Business Summit. "As far as I know he's been training and he is expected to make a full recovery.
"[Head injuries] are now more considered to be an issue and we should address it. In the past possibly if you could see three fingers rather than two you could still play.
"The doctor is there to make a decision based on his or her knowledge. Who am I to disagree with their knowledge? If a decision was made for me to come off and actually I feel all right, you have to go by the doctor's decision."
