Chelsea centre-back Wesley Fofana suffered an injury in the first half against AC Milan.
The 21-year-old was subbed off in the first half after an awkward fall.
It seemed to be a scary situation, as the Frenchman has a history of long-term injuries.
French newspaper L’Equipe has however confirmed that Fofana has avoided a major injury in the AC Milan win.
According to reports, the centre-back only has a sprained knee which became clear after a scan, and he’d be out for around four weeks.
This would help allay fears surrounding the £70m signing.
Asked for an update on Fofana after Chelsea’s 3-0 win over Milan, Potter said: “We’ll have to scan it tomorrow and see how it is.
“We’ll support him but we don’t know yet, we’ll get the scan results tomorrow. Fingers crossed. There’s nothing to report at the moment but it was the one disappointing thing of the evening.”
