Austria forward Zlatko Junuzovic has been ruled out of the Euro 2016 clash with Portugal and possibly their final Group F encounter against Iceland.
The 28-year-old suffered an ankle injury during the 2-0 loss to Hungary in Bordeaux and had to be replaced early in the first half.
Austria team doctor Richard Eggenhofer confirmed after the game that they are doing all they can to help Junuzovic get back onto the pitch.
"Zlatko has a partial tear of the outer band of the right ankle," Eggenhofer said. "The main focus is now placed on conducting therapies to reduce swelling.
"He gets ice therapy, compression bandaging and special enzymes. Zlatko is treated by the medical department virtually around the clock.
"Such an injury is always to judge by the day or by the hour – an accurate prediction of the healing process is difficult. With any luck, we'll get him for a possible second-round game, ideally, a bit earlier."
Junuzovic admitted he is devastated by the untimely injury but remains confident that Das Team can qualify for the knockout stages.
"Of course it is very bitter," the Werder Bremen player said. "From the 15th minute it was more or less an ordeal. I tried to play with it, but I was in great pain.
"Currently, my mood is very depressed, but that is the way it is. We have to see that we get off the swelling. We still have two matches. I believe in the guys, and that we will get there. Anything is possible and I will do everything that I can."
