Chelsea boss Thomas Tuchel hopes Edouard Mendy is fit for Saturday's Champions League final after making a "huge improvement" from a rib injury.
He was replaced by Kepa Arrizabalaga for the second half before going for a scan.
"We still have hope that he joins training on Wednesday and he joins the group," said Tuchel.
"He's made a huge improvement in the management of pain.
"So we need a further update on Wednesday but we hope to have him back in training."
Chelsea face Premier League champions Manchester City in the Champions League final in Porto.
