Roma forward Luca Toni will be sidelined for at least six weeks through a calf injury.
Toni was hurt during Saturday's 2-1 win at Juventus and tests confirmed Toni sustained damage to his calf muscle in his left leg.
"I am really annoyed that I have to stop now," he said. "But when I return to play I will be even more determined than before.''
Toni, who joined Roma on loan from Bayern Munich earlier this month, is expect to sit out at least nine games. The 32-year-old has struck two goals in four league appearances for Roma.
