Atletico Madrid forward Joao Felix is likely to be out of action for at least two weeks after going off midway through the 1-1 draw against Real Betis on Sunday.
The £113million man suffered a knock to his right ankle from home centre back Aissa Mandi in the closing stages of the first half and was forced off on 48 minutes to be replaced by Arsenal loanee Lucas Torreira.
The 21-year-old has suffered a succession of setbacks since joining Atletico from Benfica in the summer of 2019 and had only just recovered from another ankle injury sustained in the World Cup qualifier against Luxembourg on March 30.
