Bolton striker El-Hadji Diouf looks set to sit out the UEFA Cup game against Marseille tomorrow and could be facing a hernia operation.
Diouf suffered the injury while on African Nations Cup duty with Senegal and Jared Borgetti is standing by to come in.
Manager Sam Allardyce said: “They filled him with pain killers to get him to play and we might have to pay the price”
Playmaker Jay-Jay Okocha is set to return to the team as Hidetoshi Nakata is suspended. Gary Speed continues his recovery from a knee injury with an outing for the reserves tonight.
PROVISIONAL SQUAD: Jaaskelainen, O’Brien, Hunt, Ben Haim, N’Gotty, Jaidi, Gardner, Giannakopoulos, Faye, Okocha, Nolan, Diouf, Davies, Jansen, Walker, Vaz Te, Borgetti, Fojut.
