Jan Oblak will require surgery to correct a dislocated shoulder that could lead him to miss three to four months.
Oblak will likely miss the first leg of Atletico's Champions League tie in late February against Bayer Leverkusen.
Oblak was injured while attempting to prevent Jonathan dos Santos from scoring Villarreal's second goal and was replaced in the 40th minute by Miguel Ángel Moyá.
