Alexander Isak has not been named in Newcastle's squad for their pre-season tour of Asia.
On Saturday, Magpies boss Eddie Howe said the striker would "absolutely" be part of the squad for their games in Singapore and South Korea.
Newcastle have selected a 30-man group for the trip but said Isak "misses out with a minor thigh injury".
The Sweden international, who scored 27 goals in 42 appearances across all competitions last season, has been heavily linked with a move to Liverpool this summer.
The 25-year-old was also left out of Saturday's 4-0 defeat at Celtic as Newcastle began their pre-season fixtures.
Earlier this week, Liverpool signed Eintracht Frankfurt striker Hugo Ekitike for an initial £69m, a player for whom Newcastle had unsuccessfully bid £70m.
Newcastle, at least publicly, have maintained that Isak is not for sale and Howe said at the weekend he remains "confident" the player will still be at the club at the start of the season.
"I think it's difficult for me to give 100% clarity on any player," Howe said after their defeat by Celtic.
"Alex is happy at Newcastle. He loves the players he plays with, the staff, the team and I've never had any issue with him."
