On Wednesday, Belgium will face Canada to open their World Cup campaign. In Group F, Roberto Martinez's team will also face Morocco and Croatia.
At FIFA's request, Belgium has been obliged to make some last-minute changes to their uniform days before their competition begins.
FIFA bans Belgium's warm-up shirt after requesting that the word "love" be removed from the national team's uniform.
The OneLove armband was supposed to be worn by Eden Hazard until FIFA intervened on Monday and failed to guarantee that players would not face a warning or potential suspension for the gesture.
Hazard will follow in the footsteps taken on Monday by Harry Kane, Gareth Bale, and Virgil van Dijk by declining to wear the armband during their World Cup games.
The word "love," which is on the inside of the collar and hidden from fans' view, has also been changed on Belgium's white away uniform.
The reason for the modification is that Tomorrowland, a popular music event in Belgium, which aspires to promote diversity, equality, and inclusion, served as inspiration for the kits.
Stefan Van Loock, a representative for Belgium, asserts that FIFA made the requests because of a "business relationship" with Tomorrowland.
The 'o' of 'love' on Belgium's away kit features the festival's emblem, while FIFA asserts that the warm-up shirt's colours are a nod to Tomorrowland despite the absence of any insignia.
