Roma striker Toni ruled out two weeks
However, reports from Turin would suggest it is the recurrence of a left calf injury that had already troubled the Roma star.
It is claimed the freezing cold temperatures at the Olimpico, where it is -5 degrees Celsius, aggravated the muscle.
If it is only a minor lesion, then Toni will be sidelined for around two weeks.
If tomorrow's tests show a more serious lesion and therefore a calf strain, he could well be absent for a month.
