Lazio midfielder Stefano Mauri will be sidelined for three weeks in order to recover from a herniated disc.
A recurring back problem has limited former Italy international Mauri to just four Serie A starts this season.
A Lazio statement read: "We have decided for Mauri to undergo a non-surgical procedure based on radio frequencies to deal with a herniated disc.
"This will be carried out over the new few days. After that Mauri will have to rest for a week before he can begin the recovery process.
