Newcastle winger Allan Saint-Maximin is in transfer talks with an unnamed club as Eddie Howe acknowledged the "impact" of Financial Fair Play on the Magpies.
The Frenchman, who joined Newcastle from Nice in August 2019, has been linked with a move to Saudi Arabia.
Saint-Maximin, 26, missed Newcastle's 2-1 friendly win at Rangers, and Howe said he had "no issue" with the player.
"He's in early discussions over a potential move away. That's why he wasn't here," Howe said.
"It's doubtful he'll join us on the tour of America. I don't think Maxi necessarily wants to leave, but he may feel it's the right time for him to move.
