Michael Ballack and Juliano Belletti are both out suspended when Chelsea take on Stoke on Sunday afternoon.
The Blues will be looking to book their passage into the semi-finals of the FA Cup by defeating the Potters but will have to do it without Ballack and Belletti who were sent off against Manchester City last week.
Elsewhere, Ricardo Carvalho is doubtful after picking up a slight hamstring injury on international duty with Portugal in midweek, while Hilario will again fill in for Petr Cech who is recovering from a calf injury.
Defender Yury Zhirkov also faces a late fitness test on his calf injury, while Jose Bosingwa has been ruled out for the rest of the season with a knee injury.
