Jacob Ondrejka suffered a fracture in his left calf when he injured himself in Saturday's preseason match between his Italian club team Parma and the Bundesliga team Werder Bremen at Parkstadion in Zell am Ziller, Austria, reports Gazzetta di Parma.
The 22-year-old former Elfsborg player was carried out on a stretcher in the match after injuring himself in a tackle, according to Aftonbladet.
Winger Ondrejka, who scored five goals in twelve Serie A matches last season, is expected to be out of play for a longer time.
