Diamond is an old friend of McIlroy
Rory McIlroy & # 39; s caddy Harry Diamond will be quarantined in Florida for two weeks, making him available for the return of the PGA Tour on June 11.
Players and caddies based outside the United States must be quarantined in America before resuming the season.
World number one McIlroy plays at the Charles Schwab Colonial in Texas – the first PGA Tour event since March 12 due to the Covid-19 crisis.
"We will be able to get Harry on the bag," said McIlroy from Northern Ireland.
Diamond would fly to the US on Sunday and stay in Florida.
"We have a guesthouse where he can quarantine and make sure he does all the necessary things he needs to do in the coming weeks to become a caddy," added McIlroy.
"The only difficult thing is that he will have to quarantine here for two weeks and then it seems that on the other hand he will also have to quarantine for two weeks.
" So for a three-tournament stretch it's actually seven weeks for him, but hopefully some of those rules can be lifted between now and then. "
UK government guidelines state that people who are after June 8 must isolate themselves for 14 days.
After joining Dustin Johnson, Rickie Fowler and Matthew Wolff had joined a Florida charity game, McIlroy is looking forward to a return to competitive action in Texas.
The Holywood resident returned to number one in February for the first time in five years and he hopes for his good shape before the closure will continue.
"It will be different. Obviously there will be no fans, but there will still be the normal things you would expect, such as TV cameras, "he said.
" I look forward to playing again , go back and compete. The PGA Tour has taken the necessary precautions to ensure that we can play in a safe environment. "
