Machida, a 39-year-old featherweight who has gone 3-2 over his MMA career, will meet Mario Navarro on the prelims of Bellator 160.
The last time Machida was in action came at Resurrection Fighting Alliance 15 when he delivered a decision win over Dima Gerasimov. He signed with Bellator in late 2014.
Navarro sports a 4-4 mark and has not fought since 2014 when he was bested twice. He did compete for Bellator in 2012, losing to Anthony Bain.
Bellator 160 takes place August 26 from the Honda Center in Anaheim, as Patricio “Pitbull” Freire meets Benson Henderson in the main event on Spike TV.
