Bolton’s Fabrice Muamba is critically ill and will remain in intensive care until at least Monday morning.
The midfielder, 23, is at the London Chest Hospital’s heart attack centre after suffering a cardiac arrest during Saturday’s FA Cup tie at Tottenham.
At 2030 GMT on Sunday the hospital said Muamba remained in intensive care and is being kept sedated.
Bolton chairman Phil Gartside said:
“I ask for everybody to keep Fabrice in their prayers and thoughts.”
In a statement on the club’s website, Gartside added:
“The staff at the London Chest Hospital have been nothing short of exceptional and I would like to thank them all at this ongoing critical time. The support that we had yesterday from Tottenham and our own fans was fantastic – the staff, the fans, the players and the officials at the game – it was unbelievable.”
Speaking outside the hospital earlier on Sunday, Bolton manager Owen Coyle said:
“From our end, and on behalf of the family, we certainly want to say thanks to everybody. Everybody is praying for Fabrice which is very important and that has been a real source of strength to the family. We know it’s such a difficult time for everybody involved, our thoughts are with Fabrice’s family.”
Coyle had earlier stated:
“It’s very serious. There’s no getting away from that. God willing, he makes it through.”
Bolton’s Premier League game at Aston Villa on Tuesday has been postponed.
