The American is keen to move on in the January transfer window and now appears to have attempted to force through his exit
Jermaine Jones is set to miss Schalke's training camp in Qatar as he considers a move away from the Veltins-Arena.
The United States international has been a regular feature in the Schalke team this season, but has attracted criticism for his attitude in some fixtures.
And the 32-year-old appears to have decided his future lies elsewhere, with S04 releasing a statement to explain his omission from their travelling party.
"The midfielder, who is under contract at Schalke 04 until the summer of 2014, has asked sporting director Horst Heldt to allow him a change for the second half of the season," it read.
"To consider other options the 32-year-old will not travel to Qatar."
Striker Klaas-Jan Huntelaar will also remain in Germany as he continues his recovery from a knee injury.
