The players' union cautions that there is an increased risk of injury at the World Cup in Qatar.

Lack of preparation time will be a major role in putting players at risk, according to the union, especially with final games in leagues like the Premier League taking place just a week before the event. Other issues include the impact of the hot weather and the players' increased workload in an already shortened season, which raises the possibility of injuries delaying not just the final phases of the World Cup but also the remainder of the club season.
"I believe the chance [of injury] is increased as well as the risk of tiredness during the next four weeks, and that players might not be available when the biggest matches are played," said Jonas Baer-Hoffmann, general secretary of Fifpro. Compared to prior World Cups, I believe the likelihood of it is definitely higher. Even though players are giving it their best, and even though we may witness certain nations playing spectacular football, the likelihood of injury and fatigue-related performance limitations is rising. Despite this, the World Cup may still be incredible because of how hard the players are working. The scientific community agrees on that.
