The Belgium international winger lasted just 16 minutes on the field as Diego Simeone's side slipped to a 1-0 defeat in their latest La Liga outing
Yannick Carrasco suffered a collarbone injury as Atletico Madrid suffered a rare home defeat in La Liga on Tuesday, with Roberto Soriano's late goal snatching a 1-0 victory for Villarreal.
Carrasco damaged his right clavicle and had to be replaced just 16 minutes after coming on as a substitute for Nico Gaitan, with Fernando Torres replacing the Belgium international at the Vicente Calderon.
The winger will need to undergo further tests before a prognosis can be confirmed and midfielder Koke accepted Villarreal's game plan worked to perfection as Atletico's 11-game unbeaten run in all competitions was ended on Tuesday.
