Manchester United legend Sir Bobby Charlton is recovering from surgery after being taken ill during the Laureus Sports Awards.
The 74-year-old World Cup-winner had been due to receive an award but left London after starting to feel unwell on Sunday and needed a minor operation, understood to be to remove a gallstone.
A statement from Laureus read: "Sir Bobby Charlton was unable to receive the Laureus Lifetime Achievement Award in person at the Laureus World Sports Awards in London this evening.
"Sir Bobby felt unwell on Sunday and returned to Manchester earlier for minor surgery."
United boss Sir Alex Ferguson added: "Sir Bobby is fine, but it was felt he should go back to Manchester.
"He is very annoyed not to be here to receive this Award.
"I'll be taking the statuette back to Old Trafford for him. He loves the work he does for Laureus and I know how delighted he is to have received this tribute."
