Mick McCarthy will not rush Kevin Doyle back into action, with the striker nursing knee ligament damage.
The Wolves striker suffered the setback while on international duty with the Republic of Ireland.
He broke down during a Euro 2012 qualifier against Macedonia in March and was immediately identified as being doubtful for the end of season run-in.
Medical tests confirmed those fears, with it expected that Doyle would be missing for up to two months.
He is making steady progress in his recovery from the untimely injury, but McCarthy has warned that there is still little chance of him figuring again this season.
He told the Birmingham Mail: "Doyle will be back when he's ready, he's working hard every day in training and he is getting all of the right treatment from the physios and the medical staff.
"He's progressing nicely, the prognosis at the time was four to eight weeks and things are no different now.
"With a medial ligament injury, you can come back, have the ball hit you on the end of the toe and realise you're not ready.
"I'm not saying that is going to happen, but you have to be wary."
Wolves face a crunch clash against Fulham on Saturday, with it imperative that they respond positively to back-to-back defeats against Newcastle and Everton if they are to steer a course to Premier League safety.
McCarthy added: "Losing the last two games and conceding seven goals has been hugely damaging for us but we'll find out over the next six games if it is catastrophic or not.
"I don't know how many points it's going to take on 22nd May, but this is a huge game for us.
"Sunderland have one point out of 27, and Blackburn are on a similar run, so no-one is out of it yet.
"It doesn't matter what everybody else is doing, we need points. We need to win games. Every point is going to be a prisoner."
