Liverpool boss Jurgen Klopp is unsure whether captain Jordan Henderson will be able to feature again this season.
England midfielder Henderson has been sidelined by a foot injury since mid-February and will again miss out when Crystal Palace visit Anfield this Sunday.
In previous weeks Klopp had expressed hope over the 26-year-old making a return but he could offer no guarantees fans will see Henderson in action again before the end of May when addressing a pre-match news conference on Thursday.
I don t know, he said. At this moment he cannot really train. We have to wait. If there was something else to say I would.
We are in intense talks with different medical departments. He is already not patient anymore.
It s not cool. He looks really healthy but he cannot play football. That s the situation at the moment.
There was better news over Henderson s international colleague, Adam Lallana, who has missed Liverpool s past four matches due to a hamstring problem.
Adam is in a good way, back on the pitch but still with the rehab coach, so nothing has changed there, Klopp explained.
He should be involved not sure exactly when in a normal training week by Wednesday or Thursday, something like that.
Work, sleep, repeat . another good session completed. More still to do

Klopp also has significant injury problems to ponder at centre-back, with Dejan Lovren his only fully fit senior player in the position at this stage.
Joel Matip and Lucas Leiva are nursing knocks, while Ragnar Klavan is managing a knee problem, meaning teenager Joe Gomez could be in line for his first Premier League action since September 2015.
We have a few little things from the last game which don t make it much easier, Klopp added.
There is a bit of a muscle problem with Joel Matip and Lucas Leiva, still a problem with Ragnar Klavan it was a really small problem with a ligament but there still may not be enough time before Crystal Palace, so it will be interesting. But it looks good at the moment.
It s not 100 per cent that Luc cannot play, it s not 100 per cent that Joel cannot play, it s not 100 per cent that Ragnar cannot play but they are not in training at the moment.
Joe Gomez played on Monday for the Under-23s, played well again, and has made big steps in the last few weeks, so maybe we have to try this pair, we will see. I don t know at this moment.
