He wrote: "Worried sick for my former teammate and great friend Jackie McNamara who collapsed at home Saturday with a bleed on the brain.. my thoughts are with his wife Samantha and the children".

Thousands of supporters from across the country also provided their messages of support for McNamara who spent 10 years at Celtic.

One wrote: "In my thoughts. My favourite Celtic player." Another added: "My thoughts are with him n his family".

One person said: "God bless Jackie and all strength to him and his family". A fourth responded to Hartson's post: "Oh my goodness, that's awful news. Praying for a safe recovery".
