Lazio striker Stephen Makinwa has been ruled for the next month with a thigh injury.
The Nigerian picked up the problem during Sunday's 1-0 victory over Atalanta, just seven minutes after coming on as a substitute.
Scans showed the injury to be quite substantial, and Lazio's medical staff have ordered him to rest for the next month.
The news will come as a massive blow to Makinwa, who has struggled to establish himself at the Stadio Olimpico since his summer move from Palermo.
Lazio boss Delio Rossi will also be upset, with injuries starting to mount within the squad.
