Former Scotland international footballer Jackie McNamara has been rushed to hospital after he collapsed on his own doorstep with a suspected “bleed on the brain”.
The former full-back and manager is understood to have collapsed at his home in York on Saturday.
The Celtic and Aberdeen star, who is from Glasgow, was taken to a hospital in the city before being transferred to a facility in Hull.
Friends of his family say he is undergoing surgery, with fellow Celtic icon, John Hartson, saying the 46-year-old has a ‘”bleed on the brain”.
Taking to Twitter, Mr Hartson said: “Worried sick for my former teammate and great friend Jackie McNamara who collapsed at home Saturday with a bleed on the brain.”
He added: “My thoughts are with his wife Samantha and the children.”
