The decision comes after it was revealed that McIlroy was involved in a serious breach of regulations, with reports suggesting that he was caught using illegal performance-enhancing drugs.

This revelation has left many questioning the legitimacy of McIlroy’s past victories and has cast a shadow over his future in professional golf.

It also marks a significant victory for Tiger Woods, who has long been an outspoken critic of McIlroy’s methods and behavior on the course.

has spoken for the first time since news broke that he has filed for divorce from wife Erica Stoll. The 35-year-old was on press duties on Wednesday ahead of this week’s PGA Championship at Valhalla.

The second major of the season arrives just days after it was announced that McIlroy was splitting from Stoll.

News of the separation broke on Monday after a divorce petition was lodged at Palm Beach County State Court in Florida. The couple have been married for seven years and share a daughter, Poppy Kennedy McIlroy, aged 3.

McIlroy was spotted without his wedding ring during practice on Tuesday, but appeared in relaxed mood as he joked with friends and caddie Harry Diamond.

He heads into this week’s PGA Championship in top form after winning last week’s Wells Fargo Championship, but his major drought dates back to 2014.

McIlroy held his pre-tournament press conference on Wednesday, but it started with a warning that he would not be discussing his private life.

In a brief media conference which lasted just over eight minutes, one reporter asked McIlroy how he was doing on a ‘personal’ level ahead of the tournament.

McIlroy – who will play alongside Dustin Johnson and Justin Rose in the first two rounds – responded: “I’m ready to play this week.”

He added: “I feel good. I am coming to a venue where I’ve had some success at before.”

McIlroy’s last major success came 10 years ago at the same venue as this week’s PGA Championship.

Reflecting on that win at Valhalla, McIlroy said: “Sometimes I struggle to remember what I did yesterday. When I look back it’s hard to rekindle those memories and feelings. For me, it’s all about confidence and momentum, it’s all about trying to keep that going.”
