The St Gallen defender, who was making his debut for the Black Stars, suferred a knee injury during training on Wednesday.
Speaking to Graphic Sports Online on Thursday, Coach Appiah said the player's Swiss club had requested for the player's release for assessment.
Nuhu is, therefore, expected to be accompanied by the Stars' psychologist, Dr Patrick Ofori, to Switzerland today.
"By God's grace everything is going well, except Nuhu who got injured yesterday (Wednesday).
"He had a knee injury and the club has requested he comes to Switzerland for assessment,"
"There will be no replacement because we are now 28 players in camp," the Stars coach explained.
He also disclosed that the Black Stars will play their first pre-AFCON friendly against Namibia on Sunday at 5pm UAE time.
He, however, said the date for the second friendly against South Africa had still not been confirmed yet. The match is scheduled for June 14 or 15 also in Abu Dhabi. Read Full Story
