Right-back Debuchy returns following a one-game ban, while centre-back Williamson makes his first appearance since the Magpies exited the Europa League at the hands of Benfica a month ago.
Those are the only two changes from last weekend's goalless draw at West Ham, with Danny Simpson dropping down to the substitutes' bench and centre-back Williamson ruled out through illness.
On the substitutes' bench alongside Simpson there are places for James Perch, Vurnon Anita, Gabriel Obertan and Adam Campbell, while there is also a welcome return for French playmaker Sylvain Marveaux, who has missed the last four weeks with a groin injury.
