Aston Villa have major injury doubts over midfielders Stiliyan Petrov and James Milner ahead of Wednesday night's Barclays Premier League encounter at West Ham.

Petrov suffered a shin injury and Milner picked up a calf problem during Saturday's 1-1 draw against Everton at Goodison Park.

Manager Martin O'Neill rates both as doubtful while midfielder Craig Gardner is unavailable due to a groin injury. Nigel Reo-Coker and Fabian Delph could deputise if Petrov and Milner miss out.

O'Neill will definitely have to make a change in defence as Carlos Cuellar is suspended after being sent off at Everton. Luke Young and Habib Beye are vying to step in at right-back.

Scott Parker will return for West Ham after serving a one-game ban.

Hammers captain Parker will take his place in central midfield but fellow anchorman Radoslav Kovac is suspended as a result of his sending-off in the 2-2 draw at Sunderland on Saturday.

Manager Gianfranco Zola has no fresh injury setbacks but Kieron Dyer is still out with a hamstring problem while Dean Ashton (ankle) and Luis Boa Morte (knee) are long-term absentees.

Teams:

West Ham (from): Green, Kurucz, Faubert, Da Costa, Gabbidon, Daprela, Tomkins, Upson, Ilunga, Spector, Noble, Parker, Behrami, Collison, Payne, Jimenez, Diamanti, Cole, Hines, Stanislas, Franco.
