It's a double defensive boost for Juande Ramos as the pair have been missing alongside fellow defenders Anthony Gardner and Benoit Assou-Ekotto.
Ledley has been out all season as he's recovered from a knee injury while Ricardo has been out since the start of October following ankle surgery.
Development coach Clive Allen said: "It's great to see both Ledley and Ricardo back and this will be a good test for us, up against a Fulham side that beat Portsmouth 4-0 last week and playing at Craven Cottage."
Wayne Routledge is also in the squad and Jamie O'Hara is back in reserve action after a recent loan spell at Millwall in League One.
However, Clive is without Leigh Mills (ankle), Troy Archibald-Henville (hip) and Kieran McKenna (groin).
Squad: Alnwick, Forecast, Riley, Dervite, Hughton, King, Rocha, Martin, Routledge, Rose, Pekhart, Dawkins, Berchiche, Hutton, O'Hara, Townsend.
Ledley King and Ricardo Rocha return from injury as our reserves take on Fulham at Craven Cottage tonight (Tuesday December 4, 7pm).
