Lazio have suffered an injury scare ahead of their UEFA Champions League clash against Real Madrid.
Striker Tommaso Rocchi picked up an ankle problem in the 1-1 draw with Reggina on Sunday.
He will undergo scans on Monday to determine the full extent of the injury, but coach Delio Rossi admits he is not hopeful.
"Rocchi suffered an ankle problem and we don't know his condition," Rossi told the Italian press.
"We will see. Surely this injury is a problem."
