Roma captain Francesco Totti is a doubt for this weekend's eagerly anticipated derby with Lazio.
The talismanic No 10 had a scan on Thursday after he complained of a groin injury.
Results showed that he has stretched it and there are doubts as to whether he will be fit in time.
If Totti is ruled out, his place in the starting XI will be taken by Marco Borriello.
Totti hasn't played in either of the two derbies that have already been played this season.
However Roma have won in his absence on both occasions.
