Roma captain Francesco Totti could miss the start of the Serie A season with a thigh injury.
It is the latest blow for the 32-year-old, who has struggled with injuries over the past few years.
Totti was forced to pull out of Roma's friendly yesterday and will undergo tests over the next few days to determine the seriousness of the problem.
Coach Luciano Spalletti said: ``At the moment it seems it's nothing serious but there is some swelling.''
Totti is Roma's record goalscorer, having netted over 200 times for the Giallorossi.
The former Italy striker has spent his entire career with the capital club and recently signed a new deal which will take him to 2014.
