William Saliba, the French centre-back, has left the World Cup semi-final match between France and Spain in the first half due to an injury.
The 25-year-old was unable to continue playing as he experienced a sudden problem with his back, and was replaced by Maxence Lacroix.
The severity of the injury is currently unknown, but it's concerning that Saliba was taken off the field immediately despite the issue arising without anyone around him.
Saliba has been a key player for France at the World Cup, and his removal from the game has left his team trailing 1-0 to Spain.
This is not the first time Saliba has struggled with back problems, and there were concerns about his fitness ahead of the tournament.
Saliba's injury has sparked fears that he may require surgery after the World Cup, which could impact the start of the new club season with Arsenal.
Arsenal supporters will be worried about the length of time Saliba will be out, and the potential difficulties in replacing him.
