Taylor is back in full training after two years on the sidelines, but the Foxes game has come too early for his return.
United are desperate for a man capable of producing good dead-ball kicks that have a purpose, and that is Taylor's speciality.
The 30-year-old utility player has had a series of operation after twice rupturing his cruciate ligament.
Instead he will play in Monday afternoon’s Under-21 Premier League fixture against Brighton at Whitley Park (1pm kick-off).
Alan Pardew: “Ryan Taylor will be fit, but I don’t think he’s ready to be involved in this game yet.
“He hasn’t really played a full competitive game yet.”
