Previously, returning on May 18 was the aim, but the escalating coronavirus pandemic has made that impossible.

All three events timetabled for the window between those two dates - the Charles Schwab Challenge, the Rocket Mortgage Classic and the Memorial Tournament - have been moved to later dates.

The Charles Schwab Challenge in Texas is now scheduled to begin on June 8, with no spectators present.

If things go to plan, it will be the first tournament post-resumption.

The Canadian Open, which was due to begin on that date, has been cancelled.

Should the PGA Tour be able to resume when it is now planning to, at least the first four events will be played without any members of the public admitted to watch.

The RBC Heritage in South Carolina, which had been cancelled, has been added to the schedule to run from June 18 to 21, with that window opened up when the US Open was postponed until September.

In another move designed to increase playing opportunities, the field sizes at numerous events have been increased, although the Barbasol Championship in Kentucky - designed to run a the same time as The Open Championship - has been cancelled after The Open suffered the same fate.

Players, caddies and others who make their living from golf have seen incomes dry up following the pandemic, while tournament organisers and sponsors want to minimise losses by having events take place, even if they cannot do so at full capacity.

The PGA Tour has also unveiled a re-jigged scheduled for the 2020-2021 season - which begins on September 7 - following two majors being relocated.

The 18 weeks begining with the Safeway Open in California will feature two Majors - the US Open and Masters - as well as the Ryder Cup and 13 FedExCup events.

However, with the United States accounting for more than 700,000 confirmed coronavirus cases, it remains to be seen when it will be deemed safe and responsible for golf to return and it is possible that even these events in second half of 2020 cannot go ahead.

The PGA Tour has been suspended since last month, when the Players Championship - often referred to as men's golf's fifth major - was cancelled after one round because of the coronavirus outbreak.
