Phil Mickelson, 52, was one of many superstars to make the leap to the new LIV tour earlier this year.
For the trouble, he is said to have received over two billion kroner from the Saudi financiers behind the project.
The PGA Tour responded by suspending Mickelson and the other defectors from further play at their former home course.
This was not appreciated by a number of the new LIV players who banded together and filed a lawsuit against the US-based tour.
Eleven players put their signature on the atmosphere, including superstars such as Mickelson, Abraham Ancer and Bryson DeChambeau.
Suspended after attempted recruitment
In Mickelson's case, he was banned from the PGA Tour for two years back in March after it was revealed that he worked to recruit players to the LIV Tour.
This should have caused the 52-year-old to proceed with a lawsuit.
"Mickelson's illegal two-year suspension from the PGA Tour has caused him great professional damage, both financially and commercially," the application said.
But now Mickelson has asked to have his name removed from the lawsuit, writes the AP news agency, among others, and he is joined by Ian Poulter, Hudson Swafford and Talor Gooch.
Since then, Abraham Ancer, Carlos Ortiz, Jason Kokrak and Pat Perez have also withdrawn, leaving only three names: Matt Jones, Peter Uihlein and Bryson DeChambeau.
