Lionel Messi suffers ligament damage
Messi was stretchered off following a late challenge by Tomas Ujfalusi in the 2-1 win at the Vicente Calderon, an incident that saw the Atletico defender sent off.
Messi will undergo more tests on Monday determine the full extent of the injury but, according to the Barca website, the first examinations of the Argentinian's ankle showed just ligament damage.
Barca coach Pep Guardiola said after the match: "He'll be having more tests on Monday, but in principle a break has been ruled out.
"He's injured and the doctors will tell us how he is. Let's hope the first diagnosis is correct and we can help get him fit again. He's very sad and in tears. These things happen in football."
