O'Malley (12-0, 4-0 UFC) announced on his YouTube channel Saturday that he has signed the bout agreement, and Vera (15-6-1, 9-5 UFC) told ESPN's Ariel Helwani he also has signed.
"I'm in fight camp as of today," O'Malley said. "I'm looking to be champ next year."
O'Malley lost two years of his career before the Quinonez fight due to failed drug tests, which the United States Anti-Doping Agency (USADA) ultimately ruled were consistent with unintentional use.
Vera had a five-fight win streak snapped by a controversial unanimous decision to Song Yadong on May 16.
