"Combining the NFL with Caesars' expertise in world class entertainment will provide our fans unique experiences both here in the United States and abroad."

The Colts' relationship with Caesars comes through Indiana Grand Racing & Casino in Shelbyville and Harrah's Hoosier Park Racing & Casino in Anderson.

"(They) have been corporate partners with the Colts for some time now," Colts Vice President of Communications Steve​ Campbell told IndyStar in an email. "They've gone through several ownership changes over the years, but now are part of the Caesar's family."

Caesars other NFL relationships are with the Atlanta Falcons, Baltimore Ravens, Chicago Bears, New Orleans Saints, Oakland Raiders and Philadelphia Eagles. None of the relationships, according to the NFL's release, deal with "sports betting, daily fantasy or hotels/resorts." They only deal with the "Casino category."

"All of us at Caesars Entertainment are thrilled to be the first-ever casino partner of the NFL, the most prominent sports league in North America," said Mark Frissora, president and CEO of Caesars Entertainment, in the release. "Combining the league's 180 million fans with our 55 million Total Rewards loyalty program members will expose millions of people to the exclusive and exciting year-round opportunities at our properties."
