He's back. The former UFC heavyweight champion isn't just a coach on this upcoming seas on Spike TV's "The Ultimate Fighter". He's also going to be a guest on NBC's "Late Night with Jimmy Fallon" this Thursday:
Former UFC heavyweight champion Brock Lesnar will appear on Late Night with Jimmy Fallon on Monday, March 28th to discuss his career and his stint as a coach on the upcoming season of The Ultimate Fighter, which premieres Wednesday. "Late Night with Jimmy Fallon" airs on NBC at 12:35 am ET/PT.
This week, another fighter will make his late-night talk show debut, as UFC light heavyweight champ Jon Jones appears on "The Tonight Show with Jay Leno" at 11:35 pm ET/PT Thursday, March 24.
Jimmy Fallon's show has been welcoming towards the UFC, having twice (I believe) had UFC President Dana White on the show. Naturally, Fallon's show is more in line with the UFC's core demos than Jay Leno's. Leno, however, has the significantly larger audience.
