Scotland players will all wear a kit with a special added detail for their World Cup opener against Haiti.
Eagle-eyed viewers will notice a 'Debut' badge on each Scotland kit for the match against Haiti.
Every player featuring in their first World Cup, for every nation, will wear the special patch for their first match in the tournament.
With Scotland having waited 28 years for a return to the finals of the competition, every player in Steve Clarke's side is wearing the sleeve patch against Haiti.
The badge, which shows the World Cup trophy, simply reads: "Debut. FIFA World Cup."
The added detail won't feature for matches against Brazil or Morocco for players who were involved against Haiti. Debutants will wear the patch whenever they first feature.
As first reported by the BBC, the debutant badge is part of a FIFA link-up with Fanatics, who make Topps trading cards.
It's thought the badges will be removed after the match and used to make limited edition collectables.

Similar marketing techniques have been used in the MLS since 2024, with patches worn on the chest of player shirts above the club crest.
The cards made using the unique badges were then sold in 'Chrome MLS' hobby boxes at a price of around $120.
The MLS cards were also signed by the players, but it's not known if this will be the case for World Cup badges.
The Fanatics deal is set to come into action in 2031, meaning the debut patch collectables will not be on sale until after that date.
