PGA Tour CEO Brian Rolapp confirmed on Thursday that from 2028 the Tour Championship will be played across two weeks, at two different courses, and adopt a head-to-head format.
World number two Rory McIlroy expressed his support for the decision to introduce matchplay to the end-of-season play-offs.
The Derry-born golfer stated he feels the organisation is providing what fans have been requesting.
McIlroy admitted he was unaware of the plans prior to the announcement.
He described the structural alteration as a significant move in the right direction.
Rolapp noted that the event will now span a longer period with multiple venues involved.
The change marks a departure from previous single-day formats used for the championship.
McIlroy highlighted his own experience winning back-to-back Masters titles as context for his views on tournament structure.
No further details regarding specific course selections or seeding criteria were provided at this stage.
