Roma's Kevin Strootman will undergo further surgery after aggravating a long-standing knee injury at the weekend.
Roma midfielder Kevin Strootman requires further surgery on his knee after aggravating the injury in the 1-1 draw with Fiorentina on Sunday.
Strootman was substituted in the 34th minute at the Stadio Artemio Franchi - just his sixth Serie A appearance since returning from an anterior cruciate ligament injury, which he sustained in March last year and missed the World Cup due to.
Coach Rudi Garcia played down the injury, but the club confirmed on Thursday that Dutchman will go under the knife on Friday.
A statement revealed: "Yesterday Kevin Strootman underwent further diagnostic procedures with professors Van Dijk and Kerkhoffs, who previously operated on him.
"The examination revealed a mass of fibrous tissue (known as Cyclops Syndrone), which it is advised should be removed.
"The player is due to undergo arthroscopic surgery in Amsterdam tomorrow, during which the ligament will also be assessed."
