The operator and tribe, respectively, won't be finding themselves stuck between a Hard Rock and a hard place any time soon... with the duo signing an agreement to launch mobile sports betting in the state of Arizona.
The Grand Canyon State recently posted impressive sports betting numbers for the month of November: $50m in gross gaming revenue from handle (total wagers) of $470m.
In so doing, the state became the quickest in the US to hit $1bn in total handle since launch.
The Hard Rock Sportsbook is currently live in New Jersey and Iowa, with Arizona the latest to add to the growing list.
Brian Parrish, Interim CEO of the NNGE, said: "Mobile sports and event wagering is an important new offering that we're excited to introduce.
"The Hard Rock Sportsbook mobile sports wagering platform and our brick-and-mortar operations will offer a broad range of wagers, marketing promotions and cross-marketing offers that will be unique to the Navajo and Hard Rock brands."
Marlon Goldstein, Executive Managing Director & CEO for Hard Rock Digital, added: "We're thrilled to partner with the NNGE to provide Arizona sports bettors with a fun and engaging gameday experience through the Hard Rock Sportsbook mobile app.
"The Hard Rock brand is known worldwide for legendary hospitality and entertainment, and we're excited to deliver those experiences to Arizonans digitally with unrivaled mobile sports betting."
