Rory McIlroy has questioned whether the European golfers who decided against travelling to the United States for the resumption of the PGA Tour "really care" about their careers.
The Northern Irishman is known for his outspoken comments and his latest verbal volley is likely to provoke a strong reaction, especially as it applies to several of his Ryder Cup team-mates.
McIlroy finished in a tie for 32nd at the Charles Schwab Challenge as professional golf returned from its coronavirus-enforced shutdown last week, but the likes of Tommy Fleetwood and Francesco Molinari were absent.
With ranking points on the line once again, those who choose to sit out events will suffer, but McIlroy has little sympathy for them.
"Personally, if I were in their shoes and I was asked to come over to the States and shelter in place or quarantine for two weeks before these tournaments, I would have done that," said the four-time major winner, who is preparing for the RBC Heritage in South Carolina.
"I mean, if you really care about your career and care about moving forward, you should be here, I think. Last week was 70 world ranking points for the winner, this week it's 74.
"And I get that there are different variables and families and stuff involved, but we all have the means to rent a very nice house in a gated community in Florida, and it's not a hardship for two weeks to come over and quarantine.
"I mean, it's fine. My caddie Harry came over and did it. He stayed in our guest house. The two weeks flew by.
"I honestly don't understand the guys complaining because there is a solution to it. You can come over here and do what needs to be done.
"It might seem a little harsh, but I don't get that mindset, especially if you care about your career and you want to advance."
