The Liverpool Echo says Gomes has been absent from the pre-season training camp thus far as manager Rafa Benitez has prepared his side for Sunday's fixture against Millonarios at the Camping World Stadium.
However, it can be confirmed that Gomes was set to join up with the squad separately - and he will be available for their games in the United States.
The Portugal midfielder has been linked with Benfica this week.
After taking on Millonarios at the weekend, Everton will face Mexican side Pumas in the second match of their US tour.
