(AP Photo/Jon Super)MADRID Atltico Madrid said Monday that forward Joo Flix has sprained his left knee.
The clubs said tests have shown that the Portuguese forward suffered a low grade ligament sprain and his return to training will depend on how he responds to treatment.
The club did not immediately say how long Flix is expected to be sidelined because of the injury, but he is not likely to miss many matches after the Spanish league resumes.
Teams have been undergoing group training sessions as the Spanish government gradually lifts confinement restrictions because of the coronavirus pandemic.
Flix joined Atltico in 2019 amid high expectations after signing from Portuguese club Benfica, touted as a replacement to Antoine Griezmann.
