When was the last time two elite fighters facing each other had same trainer?

I didn't realize that the trainer of Danny Jacobs--Andre Rozier-- also trained Sergiy Derevyanchenko. This prompts me to ask, when was the last time when two elite fighters fought each other for a title? Totally stumped here.

In the article below, Rozier breathes a huge sigh of relief after the fight.
