World No. 2 Rory McIlroy believes Brooks Koepka's swift return to the PGA Tour signals a decline for the rival LIV Golf league. The five-time major winner left his Saudi-backed contract early, prompting the PGA Tour to create a penalty framework for his reinstatement. McIlroy, who leads the Dubai Invitational, noted LIV hasn't made any major signings this year.

Koepka's departure is a significant blow to LIV's roster, which has struggled to attract top talent in 2026. McIlroy argued that even re-signing another major champion like Bryson DeChambeau wouldn't change LIV's fundamental product. His comments reflect the ongoing tension between the two tours, with the PGA Tour now seen as the more stable home for elite players seeking major championship access.

Meanwhile, McIlroy opened his season with a five-under 66, using new cavity-back irons for added forgiveness. The Dubai Invitational marks his first competitive start of 2026. Koepka's return, scheduled for late January, is expected to be officially ratified under the new PGA Tour rules, setting a precedent for other LIV defectors.
