Right-back Walker has joined Villa on loan from Tottenham for the remainder of the season. He spent the first half of the campaign on loan at QPR.
Villa striker Emile Heskey will start a three-match suspension for his straight red card against Sunderland in midweek.
He will also miss the derby with Birmingham at St Andrew's and the home encounter with Manchester City. Gabriel Agbonlahor is set to switch from a wide role into the main striking role.
But defender Luke Young and midfielder Fabian Delph are still sidelined with knee injuries.
