Andre Dias looks set to miss out on next week's Rome derby after the Lazio defender suffered a thigh strain.
“Tests confirm a first degree tear to the left thigh muscle,” read a statement on the official club website.
Dias definitely misses tomorrow night's game with Palermo, but crucially is also now very unlikely to recover in time for the derby.
Lazio face local rivals Roma in the Derby della Capitale on March 13.
