Chelsea skipper John Terry is a doubt for Tuesday’s Champions League last-16 trip to Paris St-Germain after limping off in the 5-1 win over Newcastle.
Terry hurt himself on landing after an aerial challenge in the first half.
Chelsea say the 35-year-old may have a small muscular injury to his hamstring and will undergo a scan on Sunday.
Blues boss Guss Hiddink said: “We have just two days to recover and it is something to think about in the future as two days of recovery is not enough.”
Fellow central defender Kurt Zouma was ruled out for six months after injuring his anterior cruciate ligament against Manchester United last Sunday.
