Everton boss Marco Silva said the Brazilian was a doubt for the Stamford Bridge fixture after he missed training on Thursday and only managed part of Friday’s session.
The Brazilian was due to take part in at least some of Saturday’s training session and it appears he has come through that as he makes the party to travel south.
However, he is still a doubt for the game and a decision will be taken on Sunday as to whether or not he will be included in the final squad.
Richarlison has scored six goals in nine Premier League matches since his summer arrival from Watford for around £40m.
When asked about the 21-year-old’s fitness, Silva said. “He is in doubt for the match. Let’s see how he will react after the individual work he did this morning.
“We know he’s important for us as a striker and as a winger. If he’s not fit there are good options for other players in his position. It’s football. The players waiting for their chance have all my confidence.”
