Sunderland will be without midfielder Enzo Le Fee for "three to four weeks" due to a hamstring injury, manager Regis Le Bris has confirmed.
Le Fee and defender Dan Ballard sustained hamstring injuries in last week's defeat to Hull, with Ballard is expected to miss up to eight weeks.
Le Fee has made an instant impact in a Black Cats jersey since arriving in January on loan from Roma, scoring one and assisting another in eight appearances but has also brought considerable quality to the Sunderland attack.
Centre-back Ballard has made 12 Championship starts, including in the three games leading up to his injury.
