Roy Hodgson says Fulham "tried every avenue" to get Tuesday night's FA Cup fifth round replay against Swansea moved to give his players time to prepare for the match.
Hodgson's side have had just a day of rest since their 2-0 defeat of Premier League strugglers and have had no training time.
"Our people tried every avenue to get the game changed so that we would have a better preparation time but unfortunately they didn't succeed," said Hodgson.
"I don't want to make any more of a fuss of it than I'm already making by saying that one day's preparation is not enough.
"That's just stating an obvious fact. There is nobody in football who thinks that playing on a Sunday in the Premier League and again in the FA Cup on a Tuesday is a good idea."
Sunday's win was made possible by the return to form of Bobby Zamora, who grabbed his first league goal since September and set up a second for strike partner Andy Johnson.
Now though, Hodgson may be forced to break up the successful strike partnership to avoid burnout, with the likes of Danny Murphy, Dickson Etuhu and Clint Dempsey also in the frame for a rest after all action displays against Albion.
"We have a high energy game and we ask a lot of our players," added Hodgson. "With only one day's rest it's going to be very hard for those players to go and give the same performance again.
"I'm not anxious to make big changes, that's not something I want to do, but it might be forced upon me because I want to put a team out that can run around for 90 minutes and work hard.
"The last thing we want to do is have players getting injured because we're asking them to do things they're not able to do."
