The Italian has been out of action since the end of 2011 after damaging anterior cruciate ligaments in his right leg twice in six months.
The 26-year-old tweeted: "Got the OK from Professor Steadman to train with the team."
Rossi joined Fiorentina in January following a five-year spell with Villarreal.
