Bellator will continue its run of tent-pole events in 2015 as the promotion is set to stage their tier one version of events on November 6, sources tell MMA Fighting. The event, titled Bellator 145: Vengeance, will be part of the promotion's return to the Scottrade Center in St. Louis, Missouri. Bellator previously held a tent-pole event at Bellator 138 in June of this year, headlined by Ken Shamrock vs. Kimbo Slice.

The event will be headlined by a featherweight title fight between reigning champion Patricio Freire and former champion Daniel Straus. Both previously and most recently competed at Bellator 138, although not against one another. Pitbull was able to get past Daniel Weichel via second-round KO while Straus submitted Henry Corrales in the second round.

Freire and Straus have fought twice previously, however, with the Brazilian the victor both times. Straus dropped a unanimous decision to Freire at Bellator 45 in 2011 and was submitted in the fourth-round at Bellator 132 in January of this year.

In the co-main event, Bellator lightweight champion Will Brooks will defend his title opposite leg lock expert Marcin Held. Brooks most recently competed at Bellator 136 in April where he bested Dave Jansen via unanimous decision. Held also competed at Bellator 136, submitting Alexander Sarnavskiy via kneebar in the third round.

Bellator staples Michael Chandler and Bobby Lashley are expected to compete on the card, but opponents for both fighters have not yet been made.
