A flyweight title bout between champ Demetrious Johnson (17-2-1 MMA, 5-1-1 UFC) and John Moraga (12-1 MMA, 2-0 UFC) is in jeopardy, according to the Nevada State Athletic Commission.

NSAC Executive Director Keith Kizer on Tuesday told MMAjunkie.com (www.mmajunkie.com) that a UFC official informed him that the bout may not happen. Further details on the bout’s status were unavailable.

Johnson and Moraga were expected to headline the TUF 17 Finale card on April 13 at Mandalay Bay Events Center in Las Vegas.

UFC officials were unavailable for comment. Johnson declined comment when reached on Tuesday.

Johnson this past month defended his title at UFC on FOX 6, winning a unanimous decision against John Dodson in the headliner of the Jan. 26 event in Chicago. Prior to that, he won the inaugural flyweight title with a split call over Joseph Benavidez at UFC 152.

Moraga has won his past two outings in the octagon. He debuted this past August with a first-round TKO of Ulysses Gomez, then followed up with a third-round submission of Chris Cariaso at UFC 155 that won him a $65,000 performance bonus. All in all, he boasts a seven-fight win streak.
