Roma captain Francesco Totti said he will undergo scans in the coming days after suffering a thigh injury in his side's 2-0 win over Napoli on Friday.
Roma's eighth win in as many games gave Rudi Garcia's men a five-point lead over Juventus in Serie A, although the Bianconeri can reduce the gap if they draw or beat Fiorentina away on Sunday.
Totti was forced off shortly after the half hour and later said: "It was a great night for us because we beat a strong Napoli team which is a contender for the top spots in the league.
"I'm sorry I had to go off. I felt pain in my thigh and just could not continue. We'll evaluate things in the coming days."
Roma's bid for a top finish this season could be boosted by their absence from European competition this season following a seventh place finish in 2013.
