UFC flyweight champion Demetrious Johnson will look to defend his title once again when he faces Joseph Benavidez at The Ultimate Fighter 18 Finale. Officials announced the bout on “UFC Tonight” Wednesday.

The card takes place November 30 from Las Vegas. It will be the main event on a night that will see Nate Diaz and Gray Maynard square off for a third time.

Johnson (18-2-1) won the vacant flyweight title by besting Benavidez (19-3) last year.

Since that time, “Mighty Mouse” has downed John Moraga and John Dodson, while Benavidez has cruised to wins over Jussier Formiga and Darren Uyenoyama.
