DAVID Dunn has missed out for Blackburn Rovers' trip to Stamford Bridge this afternoon as a virus hits Sam Allardyce's squad.

Dunn and Chris Samba both miss out, while Pascal Chimbonda is unavailable through injury and Franco Di Santo is unavailable due to being on loan at Rovers from Chelsea.

Brett Emerton comes back into the side and is expected to be the player asked to support returning striker Jason Roberts, while Gael Givet and Martin Olsson are called into defence.

For Chelsea, Joe Cole makes his first start since January as the Premier Leagur title chasers look to continue their formidable home form.
