Ledley King is out of the frame for tomorrow night's (Wednesday, February 3) FA Cup replay at Leeds United.
The central defender played two games in the space of five days against Fulham and Birmingham City and will not be considered for Elland Road.
Ledley joins the likes of Aaron Lennon (groin) and Benoit Assou-Ekotto (hip) on the sidelines with longer-term injuries Jonathan Woodgate (groin) and Carlo Cudicini (pelvis, wrist).
Roman Pavlyuchenko remains a doubt with a groin injury.
Harry reported on Tuesday. "Ledley's not fit for tomorrow but could be okay for the weekend.
"Pav has still got a problem with his groin, he's not 100 per cent right at the moment but hopefully he'll be okay.
"Aaron Lennon's still not fit, Benoit's still not ready, so we're one or two down in terms of numbers but it will be an opportunity for a couple of youngsters to come and sit on the bench.
"I will speak to John McDermott (Academy Manager) and Alex Inglethorpe (U18s coach) to see what players deserve that opportunity."
Of the new recruits, Eidur Gudjohnsen is not available for the replay because he didn't play in the original fourth round tie against Leeds. However, he will be available if we progress.
Meanwhile, both Younes Kaboul and Kyle Walker are cup-tied having played in the competition for Portsmouth and Sheffield United respectively.
