Bolton Wanderers midfielder Darren Pratley admits returning to Tottenham to replay their FA Cup tie will be difficult.
The game will be restaged after Fabrice Muamba's cardiac arrest last week.
Pratley was one of the worst affected by the trauma of seeing medics battling to restart Muamba's heart on the pitch. It stopped beating for a total of 78 minutes even though he received 15 electric shocks from a defibrillator.
"It's been the hardest week of my life, being so close to where it happened and seeing everything go on. It's been hard sleeping. When you see that close up it's not nice.
"You lose track of the days. On Wednesday or Thursday we were in and didn't really know what day it was.
"Going back there (to Tottenham) will be tough I would think, but Fabrice is on the mend and that's the main thing."Pratley said: "I don't think you do sleep when something like that happens to one of your close mates. We saw him every day and then in effect he was dead on the pitch.
