Rodgers’ men were unable to reach the last four at the first time of asking after a resolute Blackburn side held them to a 0-0 draw at Anfield on Sunday.
Liverpool are unable to take part in a replay in the next fortnight due to UEFA regulations preventing domestic games from clashing with Champions League or Europa League fixtures. An international break will further delay the replay at Ewood Park.
But Reading look likely to have to stage their replay with Bradford on March 16, just 48 hours after both sides are involved in separate league fixtures.
“I believe the (Liverpool v Blackburn) replay is early April, the 7th or 8th,” said Rodgers.
“It is certainly not what it is for Reading and Bradford. That is unbelievable.
“I feel for them, having to play Saturday and again on Monday. It is incredible. It’s unfair for both clubs with so much at stake. I feel sorry for Parky and for Steve and for the players.”
The timing of the replay against Blackburn means Liverpool face the prospect of playing four matches in a fortnight – a situation which is far from ideal Rodgers says.
“The fixtures are tough and it certainly doesn’t help. But we just deal with it and we now have to go to Blackburn and win but we are more than capable of doing that.”
Rodgers was also once again critical of the state of the Anfield pitch which he says hinders the way his side plays.
“I’ll say it again the pitch makes it tough,” Rodgers said. “You can see yourself it certainly does not help us. When it comes to playing games you certainly want it to be an advantage. If there’s any team it doesn’t help it’s us.”
But Blackburn manager Gary Bowyer believes the pitch at Anfield is far superior to the surface Liverpool can expect to play on at Ewood Park in a month’s time.
“Our players were pleasantly delighted to see so much grass on the pitch at Anfield,” he said.
“Brendan was complaining about the pitch here. Wait until he sees Ewood. It makes this look like Wembley
