Lazio have lost defender Stephan Radu for the rest of the season after he developed a back injury.
The Romania international underwent a scan today to determine the severity of the problem.
It appears he has suffered a fracture between his second and third lumbar vertebrae.
Lazio's medical staff has recommended that Radu be kept in the treatment room for between 30 and 40 days.
The Aquile do not expect Radu to play any part in their remaining five games.
