Kevin Nolan and Gary Cahill could both return for Bolton in Saturday's vital clash with Manchester City at the Reebok Stadium - although manager Gary Megson admits neither would be able to operate at 100%.
Midfielder and skipper Nolan is suffering from a persistent back injury while centre-back Cahill is still nursing a bruised foot suffered against Wigan last weekend.
Gavin McCann is another doubt for Wanderers after sustaining a calf injury in Wednesday's defeat at Manchester United, and Megson rates the defensive midfielder's chances as "50/50".
Goalkeeper Jussi Jaaskelainen is almost certainly out for the rest of the campaign with a back problem.
Manchester City expect striker Benjani Mwaruwari to be fit for the derby clash.
The Zimbabwe international has been troubled by a minor hamstring problem this week but he should be able to train on Friday as normal.
Midfielder Martin Petrov returns from suspension but Dietmar Hamann completes his two-match ban. Richard Dunne is fine to play on despite a recent shin wound but Michael Ball and Micah Richards (both knee) remain on the sidelines.
Squads:
Bolton: Al Habsi, Nolan, Davies, Taylor, Diouf, Gardner, Campo, A O'Brien, McCann, Steinsson, Hunt, Samuel, Meite, Cahill, Giannakopoulos, Helguson, J O'Brien, Rasiak, Cohen, Walker.
Man City: Hart, Corluka, Onuoha, Dunne, Garrido, Ireland, Fernandes, Johnson, Castillo, Elano, Benjani, Vassell, Caicedo, Sun, Isaksson, Geovanni, Sturridge.
