Lazio defender Andre Dias will undergo tests later today on the injury which saw his early withdrawal from the 0-0 draw with Juventus.
The 33-year-old, 12 Serie A games this season, was replaced after just 20 minutes at the Juventus Stadium on Saturday with a leg problem.
The stopper is thought to have strained a right thigh muscle that could keep him sidelined for as long as a month.
