PGA Tour player Jhonattan Vegas was reportedly denied a waiver to participate in the forthcoming Saudi International.
According to Handicap54, Vegas had asked to compete in the event that is now under the banner of the Asian Tour.
The Venezuelan has played in the previous two editions of the Saudi International, which carries a prize purse of $5m.
Players who also compete in the event are also beckoned to the kingdom by the lucrative appearance fees.
The tournament will take place over 2-5 February at Royal Greens Golf & Country Club in King Abdullah Economic City, Jeddah.
A number of LIV Golf players are scheduled to tee it up in the flagship event.
LIV's marquee signing Cameron Smith was one of the first players to commit to the event.
Johnson - who mopped up bundles of cash in 2022 with LIV - is a two-time champion of the Saudi International.
The Asian Tour also receives funding from the Saudi wealth fund - PIF - that finances the breakaway LIV Golf League.
Previously, the Saudi International was sanctioned by the European Tour. The tournament conflicts with the AT&T Pebble Beach Pro-Am.

Players were asked to commit to Pebble Beach going forward, depending on the number of appearances in Saudi Arabia.
