Atletico Madrid defender Diego Godin was substituted off with an apparent hamstring injury in the 11th minute of their match against Athletic Bilbao.
The extent of the injury is not known, but the club reported on their official Twitter account that it was a muscle injury to his right thigh.

Godin, 30, is a mainstay of the Atleti defence as well as an important part of the team's attack from set pieces.
The defender is now a doubt for Atletico's home game with Malaga on Saturday, and their Champions League semifinal first leg at Bayern Munich next Wednesday.
