Rory McIlroy, who 13 months ago, speculated that the LIV tour was "dead in the water" now admits its impact.
"LIV Golf has forced the PGA Tour to change its out-dated system for the benefit of professional golf at a high level. It already has had significant relevance because it's made the PGA Tour innovate and adapt," said McIlroy.
Last week, the PGA Tour announced some of its events will have no-cut, smaller fields which many argue mirrors LIV.
In an interview with BBC Sport Northern Ireland, the four-time major winner said LIV pushed the PGA Tour to make these changes that hopefully will consolidate its long-term future.
"There is no doubt that LIV has come along and it's benefited everyone that plays professional golf at a high level. I'm not disputing that," added McIlroy.
The LIV contingent, which includes last year's winner and Open champion Cameron Smith, are absent from the 144-man field teeing it up this week at The Players, the PGA Tour's flagship event at Sawgrass, Florida.
