FC Salzburg have been deprived of midfielder Stefan Hierländer for four months as well as in-form striker Jonatan Soriano who is struggling with an ankle injury.
Former Austrian youth international Hierländer went under the knife earlier today in an attempt to solve a recurring knee problem. The 22-year-old, whose absence will stretch into the new year, will be joined on the sidelines by Soriano after the Spaniard damaged ligaments in his right ankle during training on Tuesday.
The forward, 28, will leave a significant void on UEFA Europa League matchday three having hit a hat-trick in Salzburg's 4-0 opening-night defeat of Group C rivals IF Elfsborg. Roger Schmidt's team subsequently edged Esbjerg fB 2-1 and host R. Standard de Liège next Thursday.
