Cardiff City midfielder Aron Gunnarsson has been ruled out for the remainder of the season due to knee surgery.
The Iceland international limped off during the early stages of Cardiff's 2-0 win over Hull City on Saturday.
Gunnarsson, who joined Cardiff from Coventry City in 2011, rejected a new contract at the Championship club in November, with his current deal expiring at the end of the season.
"We can confirm that [Gunnarsson] has today undergone surgery to remove a small amount of floating knee cartilage," the Bluebirds wrote in a statement on their website.
"It is anticipated that Aron will be sidelined for a number of weeks, although fears of a more serious injury have thankfully been allayed. We wish Aron the speediest of recoveries."
The 29-year-old will be fighting to regain fitness for his country's first ever World Cup game against Argentina on June 16.
