Danilo Cataldi, Adam Marusic and Joaquin Correa are in the Lazio squad to face Fiorentina tonight, even if they are not 100 per cent fit.
It kicks off at 20.45 UK time (19.45 GMT), click here for a match preview.
The Biancocelesti lost their 21-round unbeaten run with a 3-2 thriller away to Atalanta, so need a result against the Viola to keep their title hopes alive.
Lucas Leiva, Senad Lulic, Luiz Felipe and Bobby Adekanye are still out of action.
Cataldi was expected to miss out with a muscular problem, but the midfielder is in the group named by coach Simone Inzaghi.
So is Correa, who is likely to miss out in favour of Felipe Caicedo, and long-term absentee Marusic.
Lazio squad for Fiorentina: Acerbi, A Anderson, D Anderson, Armini, Bastos, Caicedo, Cataldi, Correa, Falbo, Guerrieri, Immobile, Jony, Lazzari, Luis Alberto, Lukaku, Marusic, Milinkovic-Savic, Parolo, Patric, Proto, Radu, Silva, Strakosha, Vavro
