With Nik Lentz taking on the challenge of stopping Chad Mendes, that left Dennis Bermudez without an opponent.
UFC officials acted quickly, pairing Bermudez with Steven Siler for UFC Fight For The Troops 3 this November.
The card takes place November 6 from Fort Campbell in Kentucky. The main event is scheduled to feature Tim Kennedy welcoming Lyoto Machida to the middleweight division.
Bermudez (11-3) has won four straight since a loss to Diego Brandao in 2011. That includes split decision victories this over vs. Max Holloway and Matt Grice.
