Wesley Fofana left Stamford Bridge on crutches on Wednesday night, much to the concern of Chelsea boss Graham Potter.
The young centre-back endured mixed fortunes as the Blues dismissed Italian giants AC Milan 3-0 in the Champions League. He was on hand to open the scoring in the first-half as he prodded home his first goal for the Blues since his big-money switch from Leicester City.
However, the evening soon turned sour as an awkward landing saw him pick up what appeared to be a knee injury. Fofana attempted to play on after receiving treatment but was soon withdrawn to be replaced by Trevoh Chalobah.
