Jan 14 (Reuters) - LIV Golf's Jon Rahm, ‌Cam Smith and Bryson DeChambeau have turned their backs on a chance to ‌return to the PGA Tour, choosing to stay loyal to the Saudi-backed circuit even ‌as former world No. 1 Brooks Koepka makes a costly comeback.

Three of LIV Golf's biggest names - all major champions who qualify for the PGA Tour's "Returning Member Program" - firmly committed to remaining with LIV Golf rather than follow Koepka's ‍lead back to the sport's traditional powerhouse.
