Bobby Robson, the Republic of Ireland international management consultant, is recovering in hospital following a successful operation to remove a small tumour from his brain on Wednesday.
Robson collapsed during a game at Ipswich Town's Portman Road venue earlier this month, after which the tumour was diagnosed.
A spokesperson for the hospital said on Wednesday evening: "Sir Bobby Robson underwent an operation in Newcastle to remove a small tumour on his brain.
"The operation went very well and the tumour was completely removed. Sir Bobby is recovering in hospital where he will be attended by his consultants over the next couple of days.
"The Robson family are extremely grateful for the many calls which have been received inquiring about his condition.
"They would very much appreciate if no more inquiries were directed to the hospital and a further statement will be issued when there is more information."
