Chelsea star Eden Hazard pulled up with an injury in the early stages of their Champions League clash with PSG this week, and there were audible gasps around Stamford Bridge.
This worry echoed back all the way to his native Belgium, where they feared more bad news.
The Belgians are preparing for their first World Cup since 2002, and are currently considered dark horses to win the tournament.
Many of the 'golden generation' of Belgians ply their trade in the Premier League, but it has not run entirely smoothly of late.
Key defender Thomas Vermaelen has barely played and struggled for form when he has for Arsenal, while just last week, first choice striker Christian Benteke suffered an injury which has ruled him out of the summer tournament in Brazil.
Reserve goalkeeper Koen Casteels of Hoffenheim was this week ruled ineligible after having to undergo surgery on a shin injury, and so the last thing supporters in the country want to hear or see is star player Eden Hazard going down injured.
Hazard himself said after the game he wanted to take no risks, and in Belgian newspaper Nieuwsblade, they were already mentioning Belgium's first World Cup friendly, a game against Luxembourg on May 26.
Fortunately, the extent of Hazard's injury indicates he will be back in action before long, pending a scan to verify the seriousness, but Chelsea are hopeful of having him back in time for the semi-finals.
This meant what could have been a big panic in his homeland, was softened as soon as the news broke that his World Cup dream is not in danger - but if it had been more serious, there would be one set of supporters even more devastated than Chelsea - an entire nation.
