Joao Felix was forced off injured towards the end of the first half during Portugal‘s group stage match against Luxembourg on Tuesday night, which has set off the alarm bells at Atletico Madrid.
The 21-year-old was named in Portugal‘s starting line-up but had to be withdrawn, so Fernando Santos turned to Pedro Neto.
Joao Felix left the pitch in pain and was visibly limping, but the extent of his injury is not yet known.
