'Undeniable with Joe Buck' episode with Royce Gracie debuts tonight on Audience Network

Broadcasting icon Joe Buck is no stranger to MMA stars, and today he’ll go one-on-one with another legend.

On this week’s episode of “Undeniable,” Buck sits down with one of the most important figures in the history of the sport: Royce Gracie. On the hour-long show, Buck and Gracie will discuss Gracie’s fighting career, the MMA lifestyle, how the UFC’s eight-sided octagon came to be, women in the sport, and much more … even sex prior to fighting.

“Undeniable” is in its third season on Audience Network, which can be found on DIRECTV and AT&T U-verse. The Buck interview with Gracie airs tonight at 9 p.m. ET/PT.

Buck’s one-on-one interview show premiered in 2015 on Audience Network, and the first season featured episodes with Chuck Liddell and Georges St-Pierre, along with other sports superstars like Derek Jeter, Michael Phelps and Wayne Gretzky. Season 2’s guests included Sugar Ray Leonard and Brett Favre.

The 50-year-old Gracie still holds the record for most consecutive UFC submission victories with 11, which came in a 13-month period in the first four UFC events in 1993-94. Gracie won the open-weight tournaments at UFC 1, UFC 2 and UFC 4. (He had to withdraw from the UFC 3 tourney after winning in the quarterfinals.

A year ago, Gracie returned after an absence of nearly nine years and made his Bellator debut with a first-round TKO of Ken Shamrock. The two first fought to a draw at UF 5 in April 1995.
