Blackburn midfielder Brett Emerton is a major doubt for Sunday's Barclays Premier League clash against Aston Villa.

The Australian suffered a hamstring injury on international duty in Egypt in midweek and will be given a late fitness test.

Emerton joins a lengthy injury list including Benjani Mwaruwari (hamstring), Vince Grella (Achilles), Keith Andrews (groin), Martin Olsson (calf) and Steven Nzonzi (hamstring). El-Hadji Diouf should be fit after a hamstring problem while David Dunn is also in contention to start.

Provisional squad: Robinson, Chimbonda, Nelsen, Goulon, Samba, EH Diouf, Jones, Givet, Pedersen, Dunn, Emerton, Hoilett, Kalinic, Roberts, MB Diouf, Hanley, Linganzi, Bunn.
