The Red Devils and other teams had to finalize their lists to give to the league for the current season.
Both players, Jones and Romero, failed to get moves away from United before the transfer deadline.
They are not in manager Ole Gunnar Solskjaer's plans, and will not be in their UEFA Champions League squad either.
One who does make the Premier League list is Marcos Rojo.
The Argentine defender has not played yet this season, but he can fill in at centre-back and left-back if needed.
