Injured players are continuing their rehab at Benton.
Alongside Sean Longstaff, both DeAndre Yedlin and Florian Lejeune have been recuperating from injuries this summer.
While Yedlin had an operation on his groin, Lejeune underwent knee surgery for the second time inside a year.
It remains to be seen at what stage the trio will be reintegrated into training, but they have all been back early working hard in order to make their respective returns as soon as possible.
