Thiago Silva could miss Chelsea's crucial Champions League second-leg against Borussia Dortmund through injury.
The 38-year-old was forced off in the first-half of the London derby against Tottenham - being replaced by Wesley Fofana.
According to The Times, the Brazil defender will 'be sidelined for at least a week' as Chelsea face a crucial part of their season.
This will come as bad news to all those involved at the club as the veteran defender has consistently been a bright spark during Chelsea's poor run of form.
Silva is therefore set to be a huge miss during the must-win round of 16 second-leg.
