The Brazilian-born striker was a doubt going into last night’s Champions League clash against Barcelona and lasted less than 30 minutes at Camp Nou.
Atlético Madrid boss Diego Simeone named Diego Costa in his starting XI for the first-leg clash at Camp Nou but the decision now looks as though it has back-fired after the 25-year-old forward had to be substituted after 27 minutes.
Costa pulled up in obvious discomfort and although Simeone seemed to try to convince his player to play through the pain, immediate medical treatment was unsuccessful and he was replaced.
Atlético confirmed the injury in a statement on their Twitter account.
“Diego Costa suffered a hamstring muscle injury in his right thigh.”
It is currently unclear how long Costa will be out of action for but he is already a major doubt for the second leg at the Vicente Calderon in a weeks’ time.
