The Spanish defender collapsed to the floor after colliding with the goalkeeper just 17 minutes into the game.
He returned to the pitch after being given medical care, but felt unwell and had to be replaced by Dani Alves nine minutes later.
The 25-year-old, who returned to the starting lineup after a three-week absence, will undergo a battery of tests to learn if he has sustained damage from the challenge.
