Gonna give this a go on me own
Starting with Blackburn @ 2.2
Heres the list of absentees for Portsmouth from BBC
Portsmouth
Doubtful: James (calf), Rocha (cheek), Smith (nose), Utaka (groin)
Injured\unavailable: Belhadj (hamstring), Ben Haim (groin), Boateng, Diop, Yebda & Webber (all knee), Dindane (contractual), Hreidarsson (Achilles), Wilson (hamstring)
O'Hara does return but the back line for Pompey will be poor(er) with no Hreidarsson, Wilson, Ben Haim, Belhadj and possibly Rocha and with Ashdown in goal there will little experience in the back line and I can see a Blackburn win and nothing else.
Blackburn have a full squad to choose from bar Andrews.
