It's expected to take place in 2019 but the R&A has no plans to make an official announcement this week about the return of The Open to Royal Portrush.
The club accepted an invitation from the R&A to add the Dunluce Links to return to the rotation of courses used to host the championship having held the event in 1951 — the only staging outside Great Britain so far.
Two new holes are to be created, replacing the current 17th and 18th but with planning permission still not in place for some of the changes required,, there can be no announcement on the date for Royal Portrush this week.
The next three Opens will be played at Royal Troon, Royal Birkdale and Carnoustie in 2016, 2017 and 2018 with Royal Portrush and Trump Turnberry (despite the recent controversy surrounding Donald Trump) believed to be in line for 2019 and 2020.
The 150th Open, which takes place in 2021, is expected to be played on the Old Course at St Andrews
