Francesco Totti will be sidelined for ten days after suffering a hamstring injury, Roma have confirmed.
The news is the first blot on the season for the Roma captain, whose side have won their first eight games.
The 37-year-old striker's performances have led Italy coach Cesare Prandelli to confirm that he would be given a place in the World Cup squad on current form, while he recently put pen to paper on a new club contract.
But against Napoli on Friday, he was substituted after 33 minutes and a statement on Roma’s official website said: "Francesco Totti has undergone examinations which have revealed a myotendinous junction lesion of the ischiocrural muscle."
The statement said the player had been told to rest for ten days, after which "the injury will be reassessed."
It means he could miss the next three or four Serie A encounters, but the statement added: "The player has already commenced rehabilitation work."
Totti will sit out Sunday's trip to Udinese and the midweek clash with Chievo, and is unlikely to face Juventus on Nov. 3 -- and it is possible he will not feature until Roma host Cagliari on Nov. 25.
He is joined on the sidelines by Gervinho, another star of Roma's season so far, who has a similar injury, leaving coach Rudi Garcia with his first major selection headache of the campaign.
