If it turns out that Gunnarsson suffered a dislocated shoulder it could leave one of the Bluebirds' key men sidelined for 10-12 weeks.
Cardiff's head of performance Richard Collinge told the club's official website: "Aron is currently undergoing a series of tests and investigations to determine the extent of his shoulder injury, from which we will be able to implement a management and recovery schedule.
"Any injury is frustrating for a player, but we will give Aron the best possible support to enable a swift return to action."
