Ghana striker Samuel Tetteh started training with Austrian side Red Bull Salzburg after being promoted to play with the top-flight after just six months at the club.
The 28-year-old is currently on the books of Red Bull’s feeder club Liefering.
A wave of flu has swept through the Austrian side with several key players knocked back by the virus.
The Ghana international started training with the Red Bull Salzburg first team this week.
It’s unclear if he will be available for the side ahead of their league match against Heimo pipes Bergers on Saturday.
