It's part of Grand Ole Opry's 90th anniversary Opry Circle Throwdown. Throwdowns have been taking place with Opry stars all summer, with locations including USO tours of the Middle East and Pearl Harbor, Hawaii; summer concerts; bluegrass festivals; and more.
The wooden circle is a copy of the circle that was cut out of the Opry's original home at Ryman Auditorium and built into the stage of the newer Grand Ole Opry House.
On Sunday, as part of the festivities surrounding the game, Justin Moore and Cole Swindell have been named to the roster of the 2015 All-Star Legends and Celebrity Softball Game.
Rusty's RockFeast: Backstage With Zac Brown Band follows Rusty and his crew as they descend upon the tour city, shop for the freshest local ingredients and prepare a gourmet meal on "Cookie" -- their 18-wheel mobile kitchen.
The seven-episode show premieres July 23rd.
