MMAjunkie Radio (1 p.m. ET): WSOF 33 headliner and lightweight champ Justin Gaethje

MMAjunkie Radio kicks off at 1 p.m. ET (10 a.m. PT) with guest Justin Gaethje.

Gaethje, the undefeated WSOF lightweight champion, puts his title on the line again Friday when he meets Ozzy Dugulubgov in the WSOF 33 main event. Gaethje won the title nearly three years ago and has defended four times since then. All five of his WSOF title fights have been stoppage victories. The lone time he went to a decision in the promotion was a fight that lost its title status when Melvin Guillard came in four pounds overweight for the championship bout.

MMAjunkie Radio airs from 1 to 3 p.m. ET (10 a.m. to noon PT), live from Mandalay Bay Resort & Casino in Las Vegas. The first hour of the show is available on SiriusXM Rush (Ch. 93) from 1-2 p.m. ET. You can also listen to and watch a video stream of the entire two-hour show, including the second hour, at www.mmajunkie.com/radio.
