Images released by the Magpies pictured the likes of Matt Targett - a £15million permanent signing from Aston Villa - Allan Saint-Maximin, Callum Wilson, Dan Burn and Joelinton returning.
However, there were a number of players missing, the majority of which are set to link up with the group on Wednesday - as revealed by Eddie Howe - after their international involvement in June.
Howe told NUFCTV: “We plan to get them back in on Wednesday.
“I gave them extended time off due to their exertions in the summer. We look forward to seeing them.”
