The Six Hours of Fuji has been moved up by one week, FIA World Endurance Championship officials confirmed Friday, allowing Fernando Alonso to contest the entire 2018 calendar season although now clashing with the Motul Petit Le Mans.

As revealed by Sportscar365 last week, WEC officials had been considering a change to the Oct. 19-21 date, understood to be influenced by the Toyota-owned Fuji Speedway, in order to have its new star driver take part in the Japanese manufacturer’s home race.

Originally scheduled for Oct. 12-14, the Fuji event was pushed back by one week in the first revision of the 2018/19 schedule, to avoid a clash with the IMSA WeatherTech SportsCar Championship season-ender.

The move places the race back into the original date, thus causing issues for a number of drivers who are scheduled to contest both the Tequila Patron North American Endurance Cup races and WEC, including Harry Tincknell, Renger van der Zande, Olivier Pla and Nico Lapierre.

2018/19 WEC Schedule (Revised):

May 4-5 — Spa-Francorchamps

June 16-17 — 24 Hours of Le Mans

Aug. 18-19 — Silverstone

Oct. 12-14 — Fuji Speedway
