David Alaba left Austria's friendly against Bosnia and Herzegovina before halftime with a trainer beside him. Austria head coach Marcel Koller brought on Stefan Ilsanker after the halftime break to replace Alaba in midfield.
Just minutes before halftime, Alaba trotted after a cleared ball down the left side of the pitch, battling with Bosnia and Herzegovina's Avdija Vršajević to keep it in bounds. He then acknowledged an Austrian trainer while rubbing his thigh while lying on the ground beyond the goal line. He left with the trainer under his own power and headed into the locker room before his mates joined him after the halftime whistle.
There are no details yet on what Alaba's injury may be, if there is one at all, for Koller may have removed the Bayern Munich youngster as a precaution. Alaba played a part in every goal for Austria in their UEFA Euro qualifier last week, and with a 1-0 lead at the time, the Austria coach may not have needed his services any longer.
Alaba has already missed two months with a knee injury he suffered in the Champions League group stage in November, so another absence would certainly be a blow for the leading Bundesliga side.
