Kone was forced off after 16 minutes of Wednesday's Champions League match against Real Madrid, according to Gianluca Di Marzio.
Analysis:Kone went down with a muscular problem early in the first half at the Olimpico and was unable to continue despite treatment on the touchline, leaving the pitch in tears with his shirt over his face. Niccolo Pisilli replaced him, and the tests scheduled for the coming hours will establish the extent of the injury and any recovery timeline.
