Turkish fullback Zeki Celik was forced to exit the match with Bologna early on in the second half.
The player’s status is yet to be determined by Roma’s medical staff.
According to the latest report by DAZN, Celik suffered a tightening of the abductor muscle of the left thigh.
This indicates that the injury is not too serious, but his condition will be re-evaluated ahead of the return leg with Bayer Leverkusen on Thursday night.
