Claudio Ranieri is hoping Juventus goalkeeper Gianluigi Buffon has not suffered a serious injury.
Buffon was replaced 10 minutes from the end of Wednesday's 4-0 win over Reggina after picking up a muscle problem.
The keeper is a major doubt for the weekend's derby with Torino and Juve coach Ranieri is anxiously awaiting the results of a scan.
"Buffon felt a muscular pain and he told me he preferred not to risk staying on the pitch," Ranieri told Sky Italia.
"He will undergo scans, but he shouldn't have a big problem. We hope not."
Meanwhile, Ranieri has put his faith in Nicola Legrottaglie to compensate for the absence of Jorge Andrade.
Portuguese defender Andrade could miss the rest of the season with a knee injury, but Ranieri feels Legrottaglie can fill the void.
The Juve boss added: "Legrottaglie is an important player for us.
"Now, with Andrade's injury, it seems right to me to bet on him."
