She left the pitch in tears when Barcelona crushed Atlético Madrid away in the league with 6–0. Ewa Pajor scored one of the goals before she left the pitch.
The 28-year-old Pajor twisted her right knee in the 70th minute of the match and Mundo Deportivo shows pictures of a crying striker when she was taken off the pitch.
The newspaper writes that an MRI scan on Monday in Barcelona will provide answers on whether it is an cruciate ligament injury.
Pajor has had a brilliant start to the season and scored five goals in six league matches and was a two-goal scorer when Barcelona crushed Bayern Munich with 7–1 in the Champions League.
