Pablo Osvaldo is likely to miss Roma's game with Sampdoria on Sunday after being stretchered off in training today.
The Italy international was involved in a collision with defender Leandro Castan and had to be carried off in Friday's session.
It is, as yet, unclear how serious the injury to the forward is, but it means that new boss Aurelio Andreazzoli will abandon the 4-3-1-2 formation he was reportedly drafting.
Instead, the temporary Coach will use a 4-2-3-1 system with Francesco Totti as the lone front-man, according to Calcio news.
