(That’s right, DJ. Pose through the pain. / Photo via Sherdog) Due to an undisclosed injury, UFC flyweight champion Demetrious Johnson has been forced to withdraw from his upcoming title defense againstÃ‚Â John Moraga, which was scheduled to go down at the TUF 17 Finale (April 13th, Las Vegas). At this point, it’s unclear when Johnson will be back in action, or if Moraga will remain on the card. To make up for the loss, the UFC has booked a new fight to take the main event spot ”” a bantamweight scrap between Urijah Faber and Scott Jorgensen. Faber is coming off an impressive first-round submission over Ivan Menjivar at UFC 157, while Jorgensen snapped a two-fight losing skid by choking out John Albert at UFC on FOX: Henderson vs. Diaz, a performance that won him both Submission of the Night and Fight of the Night bonuses. Fun fact: Urijah Faber has gone 6-0 in his last six non-title fights, and 0-5 in his last five title fights. The TUF 17 Finale will also feature Gabriel Gonzaga vs. Travis Browne, Miesha Tate vs. Cat Zingano, and probably Uriah Hall vs. some other guy from the show.
