The Whites officially begin preparations for this season's return to the Premier League on Monday, July 7 with the bulk of Daniel Farke's squad set to be available to him.
Each of Leeds' three summer signings to date are expected to be involved, undergoing baseline testing ahead of the gruelling fitness schedule and friendlies to come over the next couple of weeks.
Lukas Nmecha, Jaka Bijol and Sebastiaan Bornauw will get the opportunity to meet their new teammates for the first time next week, as they, Nmecha aside, prepare to take their first steps in the Premier League.
There is uncertainty over seven members of the Leeds squad and whether they will be present, while one player who featured regularly last season is guaranteed to be absent.
