Leadbitter was a key figure for 'Boro last season and had been expected to form a partnership with recent signing Dean Whitehead in the upcoming campaign.
Djebbour is keen on a move away from Greek champions Olympiakos.
Jonathan Greening will combine being part of the Reds' first-team squad this season with a role coaching the club's Under-21 side.
