MONACO (AP) — The IAAF says CEO Olivier Gers is resigning because of a clash over commercial strategy.

Track's governing body says Gers cited "the pre-existing commercial framework" as a barrier to doing his job.

The IAAF has a long-standing global partnership with Japanese agency Dentsu, which runs through 2029.

Gers says "I have resigned so the IAAF can pursue a different commercial strategy for the sport."

The IAAF says the French official, who joined in October 2016, intends to stay with the Monaco-based organization for three more months while his replacement is recruited.
