Thomas Tuchel has confirmed Tammy Abraham is still recovering from an ankle injury.
The German says Abraham can win his way back into the Chelsea fold by working on his fitness.
"He quit training yesterday after only five minutes, during the warm-up," Tuchel reports.
"So there was no chance that he could join the squad. It is still more or less the same injury. He had a bit of a re-injury in a training accident, exactly on the same spot where the first injury was so he is in pain, and there was no chance he could join us today.
"Firstly he needs to be fit and then secondly take it step by step to good training performances and fight his way back.
"The way back for him then is to maybe be a substitute and to be hungry to show quality in training. Now is not the moment to worry about being in the first 11 because he is out now unfortunately for too many games, and it is absolutely not his fault.
"He is hungry to come back and tries all the time but this is the risk also in pushing the players to be back as soon as possible. It was an accident in training because we thought he is already in the squad today and it is nobody's fault. Now it is kind of a restart and I hope he can use the two weeks to get fit again. This is the most important thing right now."
