Sunderland defender Tyias Browning is out of Tuesday night's bottom-of-the-table Sky Bet Championship showdown with Bolton.
The Everton loanee is yet to shake off the hamstring problem which has sidelined him for the last three games, although he is manager Simon Grayson's only definite absentee.
Grayson will monitor a series of players who picked up minor knocks during Saturday's 2-1 home defeat by Bristol City as he looks to end a 10-month wait for a league win at the Stadium of Light.
Midfielder Paddy McNair returned from an 11-month lay-off with knee ligament damage as a second-half substitute at the weekend and will hope for further action, while defender Marc Wilson is close to being fit again after a groin problem.
