Rory McIlroy will replace Brooks Koepka as world number one despite not playing this week.
The four-time major winner from Northern Ireland will leapfrog Koepka when the rankings are updated following this week’s AT&T Pebble Beach Pro-AM.
Koepka and world number three Jon Rahm are also missing the event and the two-year rolling format of the ranking system will see McIlroy go top.
McIlroy will be back as world number one for the first time since 2015
