Aston Villa strikers John Carew and Gabriel Agbonlahor have both been declared fit for Sunday's Barclays Barclays Premier League clash with Chelsea at Stamford Bridge.
Carew and Agbonlahor were left out of the UEFA Cup tie with Litex Lovech in midweek as a precautionary measure as they were suffering with slight groin and thigh problems respectively.
O'Neill is expected to revert to the same line-up which has featured in the previous six league games this season.
In addition to Carew and Agbonlahor, that will also mean recalls for skipper Martin Laursen, fellow defender Curtis Davies and the midfield duo of Gareth Barry and Nigel Reo-Coker.
Provisional squad: Friedel, Luke Young, Laursen, Davies, Shorey, Reo-Coker, Barry, Petrov, Ashley Young, Carew, Agbonlahor, Guzan, Milner, Cuellar, Gardner, Osbourne, Knight, Harewood, Salifou, Routledge.
