Cristian Mijares and Rafael Marquez will square off on October 27 in Mexico, headlining a Zanfer Promotions card that will also feature a very good flyweight bout between Edgar Sosa and Sonny Boy Jaro.

Mijares (46-6-2, 21 KO) is a former super flyweight champion still best known for his bloody, dominant win over Jorge Arce in 2007, and for some time spent in the majority of the pound-for-pound top tens out there, prior to a 2008 knockout loss to Vic Darchinyan. At one point, post-Darchinyan, it appeared that Mijares was fading away, but he's rebounded nicely with 10 straight wins, including victories over Topo Rosas and Francisco Arce. His win over Rosas put the IBF 115-pound title back around his waist, but he's now competing as a super bantamweight.

Marquez (41-7, 37 KO) was most recently signed to face Wilfredo Vazquez Jr in Puerto Rico, but that fight fell through twice. Originally scheduled for August 4, it was postponed until October 6 due to a Marquez injury, and then he reportedly fell ill recently, which canceled the fight altogether. Vazquez Jr is instead facing Jonathan Oquendo this weekend.

Marquez was last seen by most losing a competitive decision to Toshiaki Nishioka in October of last year, but did knock out Eric Aiken on May 5 of this year in his last bout.

Sosa (46-7, 28 KO) was a long-running junior flyweight titleholder with the WBC, and has done well at flyweight, too, losing only to Pongsaklek Wonjongkam in October 2011. Jaro (34-11-5, 24 KO) stopped Wonjongkam in March of this year, before losing his title to Toshiyuki Igarashi via split decision in Japan on July 16.

The card will air on TV Azteca in Mexico.
