Francesco Totti and Daniele De Rossi could miss out on Roma's trip to Fiorentina after skipping training.
The two Giallorossi stars were unable to take part in the regular full training session today, confirmed a statement on the club website.
They underwent physiotherapy and trained on a personal schedule, so remain in doubt for Sunday's lunch-time kick-off.
Marco Cassetti and the suspended Mirko Vucinic are thought to be out of action, so Coach Vincenzo Montella has to revamp the squad.
In today's session, Roma tested out a trio of trequartisti made up of Rodrigo Taddei, Matteo Brighi and Simone Perrotta in support of Marco Borriello.
It means Montella has again left out Jeremy Menez, even with Totti and Vucinic absent.
