Harry Wilson is emerging as a significant doubt for the start of Wales' Nations League campaign as they prepare to return to League A.

The Leeds United forward was included in Craig Bellamy's squad to compete against Portugal, Denmark, and Norway in September and October. However, Wilson's club manager Daniel Farke confirmed on Friday that the 29-year-old has sustained a muscle injury to his quadriceps, sidelining him for Sunday’s Premier League match against Crystal Palace.

Farke stated:

"Harry Wilson is out of this game, a quad injury, he reported some problems after the last game and also during this training week."

This injury poses a serious concern not only for Wilson, who has earned 69 caps and scored 17 goals for his national team, but also for the Welsh squad as they gear up for crucial matches.

With Wilson's absence, Wales faces the challenge of filling the void left by one of their key players, which could impact their performance in the upcoming fixtures.
