Cartha Queen's Park player Moses Mazomba, 24, is due to be put on a flight to Zimbabwe after he was denied leave to stay in the UK, despite living in Glasgow since 2008.
The club have started a petition calling for him to be granted asylum and have posed for a picture with the caption 'Moses belongs to Cartha'.
Moses has played for team Cartha Queen's Park since 2009 after meeting their coach while playing in a youth league in Govanhill. He also plays for the Glasgow Falcons basketball team.
He claimed asylum following the escalations in violence during the elections in 2008 after coming to the UK for a cornea transplant.
A spokesman for the Unity Centre in Glasgow, which supports asylum seekers, said: "Moses' health has deteriorated since being detained as he has been denied access to the treatment he needs following his corneal transplant.
"He needs to see his consultant but the Home Office have refused to release him from detention to attend appointments. The doctors in the detention centre have been unable to provide the specialist treatment he needs, and if the situation continues, Moses risks losing his sight.
"His life is at risk in Zimbabwe, where he faces not only the danger of being persecuted by government forces, but also the threat of generalised insecurity and crippling poverty in the country, and his health will also be threatened by the lack of medical treatment available for his condition."
The Home Office would not comment.
