Atletico Madrid forward Diego Costa looks certain to miss Sunday's La Liga game at home to Malaga after a scan showed he has a thigh muscle injury.
Atletico's top scorer this season with 27 goals in La Liga and eight in the Champions League, Costa was unable to train with his team mates on Friday, Atletico said on their website.
Atletico are within touching distance of a surprise domestic league triumph, which would be their first since they won a La Liga and King's Cup double in 1996 with a team featuring current coach Diego Simeone.
It is one of the closest finishes to the title race in years after Madrid's second club emerged as genuine contenders to challenge the dominance of far wealthier Real and Barca.
