Sandro Tonali has taken the number eight shirt following his summer arrival from AC Milan, while fellow new signing Harvey Barnes will wear number 15.
Anthony Gordon gets the number ten shirt following Allan Saint-Maximin's departure to Saudi Pro League side Al-Ahli last week.
Teenager Lewis Miley, meanwhile, has been handed number 67; he wore 81 when he made his Newcastle United debut, becoming the youngest player to represent the Magpies in the Premier League, at Chelsea on the final day of last season.
The players have already worn these numbers throughout pre-season, and will do so again at the Sela Cup, presented by VisitMalta, where United's men will face Fiorentina on Saturday and Villarreal on Sunday. Newcastle United Women, meanwhile, take on West Bromwich Albion Women on Saturday.
Tickets for both days are available to buy here and supporters can buy shirts here or at the club store over the weekend.
