Arsenal defender William Saliba will be sidelined for an extended period after suffering a back injury while playing for France during the 2026 FIFA World Cup. The reigning Premier League champions announced the news on Wednesday, stating that the centre-back sustained the injury during the tournament in North America.

Saliba was hampered by the injury throughout the World Cup, which limited his training sessions. He was substituted in the first half of France's 2-0 semifinal defeat against Spain and subsequently missed the third-place playoff match against England.

"Subsequent specialist reviews on William’s return to London this week have confirmed that he has suffered a back injury which will require a period of rehabilitation," Arsenal said in a statement. Extensive assessments have concluded that surgery is not recommended, but the club confirmed Saliba will now begin a managed recovery programme.

"Everyone is fully focused on supporting William to ensure he is back to full fitness as soon as possible," the club added. The duration of Saliba's absence remains unspecified, but the term "extended period" suggests he will miss a significant portion of the upcoming season.

Saliba was a pivotal player for Arsenal last season, making 50 appearances across all competitions. His contributions were instrumental as the Gunners ended a 22-year wait to win the Premier League title and reached the Champions League final. His absence will undoubtedly be a blow to the team as they prepare to defend their league crown.

Arsenal are scheduled to begin their Premier League defence at home against promoted Coventry City on August 21. The club will now need to manage their defensive options without one of their key players during this crucial start to the campaign.

The World Cup saw France reach the semifinals before being defeated by eventual finalists Spain. Saliba's injury highlights the physical demands placed on players during major international tournaments and the potential consequences for their club careers.

Further updates on Saliba's recovery progress are expected from Arsenal in the coming weeks and months.
