Roma captain Francesco Totti is running out of time to prove his fitness for Sunday's capital derby against Lazio.
The forward didn't take part in this morning's training session after picking up a thigh strain before the international break.
The Roman is set to have his right leg analysed in further tests at Villa Stuart over the next 48 hours, but it's not looking good for the veteran.
Totti scored both goals in the last Serie A meeting between these two teams on March 13. The Giallorossi actually won the other derby 2-0 last term too.
There is some good news for Roma though as Fernando Gago and Simone Perrotta look to be back in shape after some fitness concerns.
