The Short Version
Saliba did play through the 2026 World Cup with a spinal fracture sustained during Arsenal's April campaign, according to detailed medical examinations reported by RMC Sport and corroborated by multiple outlets. He took daily painkillers, was visibly struggling, and was forced off in the semifinal against Spain. The fracture-specific diagnosis originates primarily from one authoritative French outlet, with surgery now reportedly being considered, but the broader claim is well-supported by the weight of evidence.
