UFC has yet to make an official announcement.
Alvarez also teased a potential bout with Pettis earlier this week.
I can't sit right Now !! Boston !! Me and Pettis ?? are You fucking Kidding me !!! East coast lets Gooooo!!! This will be something special— Edward Alvarez (@Ealvarezfight) September 9, 2015
Alvarez, a former Bellator 155-pound champion, is 1-1 in UFC and most recently bested two-time title challenger Gilbert Melendez in a close contest at UFC 188 back in June. The 31-year-old striker has picked up victories over dangerous opposition like Shinya Aoki, Patricky Freire, and Michael Chandler throughout his mixed martial arts (MMA) career.
Alvarez admitted to MMAmania.com prior to his win over Melendez that he is "two or three impressive wins away from fighting for a title."
Pettis (18-3), on the other hand, suffered a broken orbital bone in the beatdown he received from current lightweight champion Rafael dos Anjos at UFC 185 back in March. The 28-year-old phenom was then forced out of a planned scrap against former lightweight Myles Jury at UFC on FOX 16 in July because of elbow issues.
The Roufusport product defended his title once against Melendez at UFC 181 last December after snatching it away from Benson Henderson at UFC 164 in Aug. 2013.
If said lightweight scrap between Alvarez and Pettis comes to fruition, it will join a growing card featuring a bantamweight championship showdown pitting current 135-pound kingpin TJ Dillashaw against former division titleholder Dominick Cruz.
No complaints here.
