Fiorentina have confirmed Riccardo Montolivo will undergo knee surgery on November 15.
“Considering the persistent pain in Montolivo's ankle, despite the conservative therapy, the athlete will go under the knife to resolve the situation,” read a statement on the club website.
“The problem started after a trauma during the World Cup in South Africa. The operation will be performed on November 15 in Amsterdam by Professor Van Dijk.”
Montolivo has been playing regularly with the aid of pain-killing injections for the past five months.
Regular treatment was unable to halt the chronic condition, so the Fiorentina captain has opted for a radical intervention.
It is not clear how long he will be sidelined for, but it's likely to be at the very least a month.
The Viola already received bad news this week, as goalkeeper Sebastien Frey will be out for up to six months with damaged knee ligaments.
