Aston Villa manager Alex McLeish has to find a replacement for calf injury victim Alan Hutton at right-back for the home Barclays Premier League clash with Chelsea.
Eric Lichaj and utility player Chris Herd are the likely players to be in contention to replace the Scotland international who will be sidelined for two to three weeks.
Winger Charles N'Zogbia will be out for a further month with his knee setback while skipper and midfielder Stiliyan Petrov is battling to overcome a virus to face the Blues. Striker Darren Bent (ankle), defender Richard Dunne (shoulder) and midfielder Fabian Delph (ankle) remain long-term absentees while utility player Ciaran Clark is still recovering from a knee problem.
Provisional squad: Given, Guzan, Lichaj, Herd, Collins, Cuellar, Warnock, Baker, Bannan, Petrov, Gardner, Ireland, Albrighton, Agbonlahor, Heskey, Weimann, Marshall, Johnson, Stevens, Delfouneso.
