Leeds' teenage defenders Aidy White and Tom Lees have both returned from their respective loan spells at Oldham and Bury.
Left-back White, 19, made 24 appearances for Oldham during the second half of the campaign, while central defender Lees, 20, clocked up 50 appearances with Bury, winning promotion with the League Two club during his season-long stay and scoring some key goals.
Leeds manager Simon Grayson said: "They've both enjoyed successful loan spells. I'm a big believer in that if players aren't playing and they can get out and play and gain experience elsewhere then that's for the best. It's certainly worked well for Aidy and Tom.
"We've been keeping a check on them both so we know how they've done and we'll look forward to having them back with us.
"They are two players we hold in high regard so we will see where we are with them after pre-season and how things go."
Fellow Academy product Will Hatfield, a central defender, has also returned from his loan spell at York, but midfielder Adam Clayton will stay with MK Dons until after the play-offs.
