The LIV Golf players won't be able to earn world ranking points at upcoming events in Thailand and Saudi Arabia.
The series' upcoming events were not given enough notice.
The changes to the tour are being reviewed.
Inviting events will be held in Thailand and Saudi Arabia.
Changes to the membership structure and an outline of the initial series of tournaments in the 2022-23 season were detailed in the communication from the Mena Tour.
The notice of the changes given by the Mena Tour is not enough to allow OWGR to conduct the necessary review prior to the LIV Golf Invitation Bangkok and LIV Golf Invitation Jeddah.
After the review is complete, a decision will be made on awarding points to the new "Limited Field Tournaments", defined by the Mena Tour in its Regulations as "any Mena Tour-approved tournament, which comprises of a player field of less than 80 players".
The regular official Mena Tour events conducted over 54 or 72 holes with a cut after 36 holes, and its Tour Championship, typically conducted over 54 holes with no cut, are eligible for inclusion in the OWGR.
The players risk falling down the rankings and missing out on the majors if they don't get recognised by OWGR.
As part of the agreement, all LIV Golf players have joined the Mena Tour, which has been inactive since the beginning of the global Pandemic.
The LIV Golf alliance marked a very exciting day for the Tour and its players.

Two-time major winner and former world number one Greg Norman is fronted by LIV Golf and it has caused deep divisions in the sport.
