Fabrice Muamba remains in a 'critical' condition as the Bolton midfielder fights for his life after collapsing at White Hart Lane on Saturday having suffered a heart attack.
Manager Owen Coyle admitted the 23-year-old midfielder faces a 'crucial 24 hours' as medics attend to him in the intensive care unit at the specialist London Chest Hospital where he will be anaesthetised.
Bolton's forthcoming Tuesday night Barclays Premier League clash with Aston Villa has been postponed at the request of the club.
Both Wolves and Manchester United players will take part in 30 seconds of applause for Muamba ahead of their afternoon Barclays Premier League match at Molineux.
A joint statement from the Barclays Premier League club and the London Chest Hospital revealed his worrying condition is still considered to be critical.
It read: 'Fabrice Muamba remains in a critical condition in intensive care in the Heart Attack Centre at The London Chest Hospital.
'He was admitted to the hospital yesterday evening after collapsing at White Hart Lane, where he sustained a cardiac arrest during the FA Cup Quarter Final against Tottenham Hotspur.
'Fabrice received prolonged resuscitation at the ground and on route to The London Chest Hospital, where his heart eventually started working.
'As is normal medical practice, Fabrice remains anaesthetised in intensive care and will be for at least 24 hours. His condition continues to be closely monitored by the cardiac specialists at the hospital.'
Bolton manager Owen Coyle said: 'Fabrice's family have asked me to pass on their thanks for the many, many kind messages of support from not only Bolton fans but also fans from clubs across the country and abroad.
'All our thoughts and prayers are for Fabrice and his family at this time. The family would also like to thank the media for respecting their privacy at this time.'
The statement ending saying: 'No further updates are planned at this time.'
Tottenham also issued a statement on Sunday afternoon expressing their sympathy for Muamba and his family.
Spurs boss Harry Redknapp said: 'All our thoughts are with Fabrice, his family, Owen Coyle and the Club. It was the right decision to abandon the game, everybody was in a state of shock and it wouldn't have been right to carry on.
'Football is the last thing on anyone's mind when an awful situation such as this happens. All we are thinking about now is Fabrice and his family.'
Club Chairman, Daniel Levy added: 'Our thoughts are with Fabrice's family and Bolton Wanderers and we are all willing him to pull through. Events such as this put everything into perspective.
'We are immensely proud and grateful to the medical teams at both clubs, their response was immediate and professional. Our thanks also to both sets of fans for their support and behaviour.
'Too often we read the negatives about football and yet last night, at a time of intense emergency and uncertainty, we saw the true humanity and empathy of the footballing family.'
Boss Coyle, chairman Phil Gartside and skipper Kevin Davies were amongst those who accompanied Muamba to hospital.
The England Under-21 star, who is a father of one, underwent six minutes of treatment amid worrying scenes at White Hart Lane.
He was wearing an oxygen mask and was then rushed to the London Chest Hospital in Bethnal Green in east London.
Within a second of seeing Muamba fall to the ground, Bolton manager Owen Coyle shouted 'he's just collapsed' before running on to the pitch to be alongside his player amid a sombre atmosphere at Tottenham's ground.
Muamba was carried off on a stretcher and referee Howard Webb abandoned the match moments later.
It is understood captain Kevin Davies accompanied Muamba to the hospital along with Coyle.
Premier League chief executive Richard Scudamore sent his organisation's best wishes to Muamba and his family, as well as paying tribute to the medical staff at the ground.
He said: 'The thoughts of the Premier League, its clubs and players are with Fabrice Muamba, his family and Bolton Wanderers.
'We would like to praise the players, match officials, coaching staff and medical teams of both clubs at White Hart Lane for their swift actions in attending Fabrice.
'The League would also like to commend the compassion shown by the fans of Bolton Wanderers and Tottenham Hotspur.
'We hope to hear positive news about Fabrice, who is and has been a wonderful ambassador for the English game and the League at Arsenal, Birmingham City and Bolton Wanderers.'
Worried fans and players took to Twitter to give their reaction to Muamba's collapse.
Middlesbrough defender Justin Hoyte, who came through the Arsenal youth team with Muamba, posted: 'I seriously hope my best friend in football is OK. Stay strong bro please please stay strong. God is with you remember that.'
Muamba's Bolton team-mate Stuart Holden wrote: 'Praying for you Fab. Hope he's OK. Thoughts with him and his family.'
Spurs striker Jermain Defoe said: 'Pray for fab god willing he will pull through £PrayForMuamba.'
Muamba started his career at Arsenal and spent two years at Birmingham before joining Bolton in 2008.
He was born in Zaire, now known as the Democratic Republic of Congo, but has represented England from under-16 to under-21 level.
Football Association chairman David Bernstein said: 'On behalf of The FA, I would like to send our thoughts and prayers to Fabrice Muamba and his family this evening.
'Fabrice has played 33 times for England Under-21s, captaining Stuart Pearce's side during this time and is a player, and more importantly, a person we care greatly for.'
Muamba broke into the Premier League with Birmingham, with the club this morning offering their support for the midfielder.
'The thoughts of everyone at the club are with Fabrice and his family,' a club spokesman said.
'He was a very popular member of the club during his time here and everyone at St Andrew's is shocked and saddened to see what happened yesterday.'
Former Birmingham chairman David Gold said on Twitter: 'Fabrice Muamba is one of the nicest and most respectful young men I ever met in football. I'm thinking of you Fab, get well soon.'
Webb removed as fourth official at Molineux on advice of psychologist
Referee's chief Mike Riley has granted Webb a leave of absence, allowing the World Cup official to miss this afternoon's Barclays Premier League game between Wolves and Manchester United.Riley’s decision comes after consulting a psychologist who works with the Professional Game Match Officials Limited (PMGMOL).
Webb was forced to dramatically call Saturday's match off when Trotters midfielder Muamba collapsed in the centre of the White Hart Lane pitch after suffering a suspected heart attack in front of 36,000 fans and a television audience of a million with players saying they 'couldn't go on'.
The 23-year-old, who was reported to have stopped breathing, received cardio-resuscitation treatment from doctors and paramedics as shocked and distressed players from both sides looked on.
After 10 minutes of treatment, Muamba was carried from the field on a stretcher and rushed to the London Chest Hospital, where he was still being treated late on Saturday night.
