Clement does not plan on playing Dyer just yet, but is pleased to be able to take him along on the pre-season trip as he is already mobile and capable of light training.
Dyer picked up the injury in February and has been on the sidelines ever since.
“Nathan is still on the road to recovery,” Clement told the club’s official website.
“Normally the rehabilitation period for the type of injury he had is nine months.
“If that’s the case this time, he will not be fit until October.
“But Nathan is coming with us to America because unlike Fernando Llorente, he can run and is mobile.
“We have just got to be careful that we don’t push him too quickly because you can re-rupture those injuries and then you are starting from zero again.
“Apart from Nathan, everyone who is travelling will be able to train and play.”
