Two-time British Open champion Greg Norman has been disinvited by what many are now calling a “classless act” by the R&A,” ahead of their so-called ‘Celebration of Champions’ event at St Andrews.

The 67-year-old Aussie, who hoisted two Claret Jugs (1986 and 1993) during his iconic career, is currently the CEO of the LIV Golf series, the PGA Tour’s upstart rival.

In a statement that is almost assured to be used in pending and future lawsuits, as well as a current anti-trust investigation, the R&A flat out said Norman was not welcome:

“In response to enquiries regarding the R&A Celebration of Champions field and the Champions’ Dinner, we can confirm that we contacted Greg Norman to advise him that we decided not to invite him to attend on this occasion.

“The 150th Open is an extremely important milestone for golf and we want to ensure that the focus remains on celebrating the Championship and its heritage. Unfortunately, we do not believe that would be the case if Greg were to attend. We hope that when circumstances allow Greg will be able to attend again in future.”

Norman told Australian Golf Digest: “I’m disappointed. I would have thought the R&A would have stayed above it all given their position in world golf.

“[It’s] petty, as all I have done is promote and grow the game of golf globally, on and off the golf course, for more than four decades.”

Phil Mickelson, the 2013 Open Champion, will also not be attending the event, but is in the field for The 150th Open.
