The first-team players will have 'Barcelona' written across the back of their shirts instead of their names in the match against Betis, a tribute to the victims of the terror attacks in Barcelona and Cambrils.
This has been made possible thanks to a petition made by the club. The Spanish FA has given them permission to do so in Sunday's fixture.
The players will also have '#TotsSomBarcelona' (We're all Barcelona) across the front of the shirt, having been awarded extraordinary authorization by La Liga.
Added to these tributes, before the game kicks off, the Camp Nou will hold a minute's silence to remember everyone affected. The players will wear black armbands.
