Messages of support flooded in for Geoff Cook after the Durham head coach was admitted to hospital having suffered a suspected heart attack.

Durham skipper Paul Collingwood and former England captain Michael Vaughan were amongst those tweeting their support for the 61-year-old after the county - who are due to host Hampshire in a YB40 game tomorrow - confirmed his condition in a statement.

"Durham County Cricket Club can confirm that head coach Geoff Cook was taken ill at Chester-le-Street this morning," read the statement issued last night.

"Geoff was taken to hospital and is undergoing treatment for a suspected heart attack.

"The club is awaiting further news on his condition and our thoughts are with Geoff, Judith and his family."

That prompted a flood of support on the social networking site with Collingwood posting: "All our thoughts with Geoff Cook and his family. Sad sad day."

Vaughan added: "Thoughts and prayers are with Geoff Cook and his family...A great man.. Get well soon Geoff..."

England spinner Graeme Swann also took to Twitter to wish Cook well, writing: "Just heard the news about Geoff Cook. Fingers crossed for a speedy recovery for him."

Wicketkeeper Matt Prior posted: "Thoughts are with Geoff Cook and his family at this time. Fingers crossed for a full and speedy recovery."

Cook played in seven Tests and six one-day internationals for England in 1982 and 1983 and became director of cricket at Durham when they became a first-class county in 1991.

He was named as head coach in 2007, immediately winning the Friends Provident Trophy, and brought the club back to back county championship titles in 2007 and 2008. They had never won the championship before.
