The Sunderland pair have missed the last four league games through injury.
Midfielder Ndong has missed the club's last four games with a knee injury, while Jones has been absent for the same period.
It seems unlikely that either player will be fit enough for the trip to Molineux but news of their imminent returns will be a major positive for manager Chris Coleman, especially as Sunderland are in the midst of an injury crisis.
Sunderland are currently without a host of players, as Bryan Oviedo, Paddy McNair, Lamine Kone and Jack Rodwell are all sidelined in addition to long-term absentees Duncan Watmore and Jonny Williams.
Coleman, who took charge of Sunderland last month, is aware that he needs to significantly improve the club's fortunes as they are currently second from bottom in the Championship.
