For the first time, golf's governing bodies appear poised to allow for significant rules differences between elite players and other golfers as a way to combat the distance gains the sport has seen with the advancement of technology.
On Tuesday, they announced three proposed changes:
A limit on the maximum driver length from 48 inches to 46 inches. U.S. Open champion Bryson DeChambeau is one of the high-profile players who has experimented with the longest-shafted driver in order to attain more distance off the tee.
Changes to how drivers are tested for distance, which is known as the spring-like effect, and changes to how golf balls are tested by revising the conditions.
The driver-length maximum will have a one-month review period, while the other testing proposals will be reviewed over six months.
