Illness worries for Allardyce

Blackburn have a handful of players battling a virus as they prepare for their Barclays Premier League clash at Chelsea. Manager Sam Allardyce has not yet ruled any of the affected players out but will check on them before deciding on his starting XI. Striker Franco Di Santo is ineligible to face his parent club, Vince Grella remains sidelined with a thigh injury and Pascal Chimbonda is a doubt with a calf strain.
