The Norway international, Villa's top scorer for the past two seasons, missed the opening Premier League game with Wigan because of a foot injury.
Villa boss Martin O'Neill has named a full-strength squad for the trip to the Austrian capital as the midlands club look to book their place in the expanded group stages.
O'Neill came under fire from some Villa fans after sending a shadow squad to the last 32 game with CSKA Moscow last season.
Aston Villa (from): Friedel, Guzan, Marshall, Davies, Shorey, Beye, Cuellar, Lichaj, Clark, Lowry, Sidwell, Young, Milner, Albrighton, Delph, Petrov, Reo-Coker, Gardner, Carew, Agbonlahor, Delfouneso, Heskey.
