Tim Kennedy will remain in the main event role for UFC Fight For The Troops 3, taking on Rafael Natal.
Officials made the announcement on Tuesday. The card takes place November 6 from Fort Campbell.
Kennedy (16-4) was originally scheduled to face Lyoto Machida, but Machida opted to meet Mark Munoz after an injury knocked Michael Bisping out.
Kennedy earned a win in his Octagon debut over Roger Gracie earlier this year. He is a former two-time contender to the Strikeforce middleweight belt.
Natal (17-4-1) sports a 5-2-1 UFC record, including three straight wins.
