McCann missed Saturday's 3-3 home draw with Manchester City with an ankle injury manager Gary Megson has described as 'quite serious', joining Joey O'Brien and Sean Davis in the treatment room.
Sidelined: Mccann (right) will play no part against the Hammers
Ricardo Gardner, who also missed the City game through illness, is doubtful, although Megson at least has Saturday's two-goal hero in Ivan Klasnic available even though he limped off late on with a hip problem.
Team (from): Jaaskelainen, Ricketts, Steinsson, Knight, Cahill, A O'Brien, Samuel, Robinson, M Davies, Basham, Muamba, Cohen, Taylor, Gardner, Klasnic, Lee, Elmander, Davies, Al-Habsi.
