McIlroy is in the field for the WGC-FedEx St. Jude Invitational this week in Memphis, Tennessee, in the lead-up to 2020's first major – the US PGA Championship at Harding Park from August 6.

The World No.2 will play the US Open in September but has hinted he may not take part in the European Tour's Scottish Open or BMW PGA Championship in October.

"I honestly don't know if I see myself going back to Europe this year," McIlroy said.

"I don't know if I want to travel, I don't know if I want to be exposed to more things and more people.

"I'm sort of taking it week by week.

"I've got my schedule planned up until the US Open, which is obviously a couple weeks after the Tour Championship, and then I honestly have no idea what I'm going to do after that."

McIlroy said while he understood why Lee Westwood chose not to travel to San Francisco for the PGA Championship, he would return to Europe if there was a major on the schedule.

This year's Open Championship, which was due to be held at Royal St George's in Kent this month, was cancelled due to the pandemic.

"I understand their plight," the Northern Irishman said.

"I was just saying I don't know if I would travel in the fall and go and play some of these other events in Europe, but if it was a major championship, it would probably be different."

The European Tour returned this month with back-to-back events in Austria, while the British Masters last week was the first of six tournaments on the 'UK Swing'.
