Atletico Madrid's Uruguayan international defender Diego Godin has picked up a left ankle sprain during the Spanish club's midweek 1-0 Champions League win over Bayern Munich.

"After a first examination by the club's medical staff, the international (Uruguayan) is suffering from a sprained lateral collateral ligament in his left ankle," the club said in a statement Thursday.

"Additional tests will be conducted in the coming hours," it added without giving details for how long the 30-year-old was expected to be sidelined for.

The Spanish club are already without Uruguayan defender Jose Maria Gimenez, who suffered a thigh injury last weekend, and Godin's absence could prove a defensive headache for coach Diego Simeone.
