Everton will be missing key striker for Newcastle United clash as Carlo Ancelotti reveals injury latest
A minor knee injury precluded the Brazil international's involvement in the weekend draw at West Ham.
Ancelotti had hoped to welcome back the striker on Tuesday but he will miss out.
"Richarlison trained today but he still had pain so he will not be available tomorrow," Ancelotti said.
Everton are taking no chances on Alex Iwobi, who has missed the last six games.
Fellow midfielder Gylfi Sigurdsson is set to be absent again with a groin complaint, while the Toffees will make a late decision on Michael Keane.
Ancelotti added: "Iwobi is doing well but we don't want to take a risk, he will stay here to train.
"Sigurdsson is out and Michael Keane trained today, he was not so comfortable and he will be in the squad and we are going to decide tomorrow."
