James Scowcroft and Lee Hills will miss the second leg of Crystal Palace's play-off semi-final tomorrow night and a trip to Wembley should they reach the final.
Scowcroft came off the bench on Saturday against Bristol City for his first appearance since the end of March but aggravated his hamstring injury after only five minutes and has been ruled out for the rest of the season.
Manager Neil Warnock also revealed that Hills was injured in training last week, while Paul Ifill is a slight doubt for tomorrow night.
He said: "Paul was a little bit stiff on Saturday. We didn't really want to push him too hard as he had a little bit of a problem last week but I think he will be ok on that, we will know more later today.
"Lee Hills hurt his ankle and knee in training last week so I think he will be out for the rest of the season."
Kyel Reid is expected to take Scowcroft's place in the squad for tomorrow's game against Bristol City.
