Gabriele Angella will make his QPR debut in Saturday’s game against Nottingham Forest but Yun Suk-Young is not yet ready to return to the squad.
Yun has featured in recent reserve-team and Under-21 matches, having missed all of pre-season with a knee injury.
He hoped to secure at least a place on the bench against Forest but will not be considered for selection as he is not yet fit enough.
Head coach Chris Ramsey has been full of praise for summer signing Grant Hall but the centre-back will make way for Angella, who was recently brought in from Watford.
Sandro, back at the club after resolving an issue with his visa, is another player not currently being considered for selection.
The Brazilian midfielder is building up his fitness and in any case Ramsey wants to show loyalty to the likes of Karl Henry and has told Sandro he cannot expect to go straight into the first team.
Jamie Mackie, meanwhile, is still recovering from a groin problem and will miss the game against his former club.
