It was announced on Ariel Helwani's ESPN show that Del Rio is officially set to face 44-year-old Tito Ortiz in the main event of Combate Americas' debut pay-per-view on December 7 in Hidalgo, TX.
The fight will be fought at a 210 pound catchweight, and is expected to cost $39.99
The 42-year-old Del Rio, a trained amateur wrestler and former Olympic hopeful, amassed a record of nine wins and five losses during an MMA career that spanned from 2001 through early 2010.
In his most notable fight, Del Rio (fighting under a mask) was knocked out by Mirko Cro Cop in 46 seconds following a head kick, at Pride Bushido 1 in Saitama, Japan in October 2003.
Del Rio and Ortiz had a rather bizarre and awkward confrontation in August (NSFW language at this link) to set the fight up.
