Chelsea were hopeful Ramires would be fit for Sunday's Barclays Premier League match away to QPR after he missed training for Wednesday's Champions League clash with Genk.
Brazil midfielder Ramires looks certain to sit out the Group E encounter at Stamford Bridge with the knee injury suffered in Saturday's 3-1 Premier League victory against Everton.
The 24-year-old, who has been in fine form this season, hurt himself scoring his side's third goal.
