Leicester City defender Clive Clarke collapsed at half-time during his side's Carling Cup tie against Nottingham Forest.
Clarke, who is on loan at Leicester from Sunderland, collapsed in The Foxes' dressing room shortly after the referee blew for the break.
The restart was delayed by 25 minutes while paramedics attended to Clarke and his team-mates waited anxiously on pitch-side for news.
Clarke regained consciousness and was taken to hospital but the Leicester players had been shaken by the ordeal.
Forest boss Colin Calderwood and his Leicester counterpart Martin Allen agreed it was in the best interests to postpone the tie.
Calderwood, whose side were winning 1-0 through Junior Agogo's goal, made the announcement to the home crowd.
He said: "We are afraid that due to the serious illness of a Leicester player both clubs have agreed to postpone the match."
Clicky Thing
This is yet another worrying situation involving a professional footballer. No clear details have yet been released regarding this latest incident but coming so soon after the untimely death of Sevilla's Antonio Puerta it is troubling news.
There is absolutely no way these two situations can be linked but it is a very strange and sad coincidence that within the space of 72 hours two footballers have been taken seriously ill during a game.
