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.
