Alberto Del Rio is confident heading into Saturday's match against Tito Ortiz despite it being his first MMA match since 2010.
"[I'm] ready to end his career because he's going to have to retire after this fight," he said on Ariel Helwani's MMA Show Monday.
Del Rio had a 9-5 record during his professional MMA career but is better known for his spell in professional wrestling, including his time as a WWE champion.
"I keep saying this—I'm doing it for the right reasons," he previously said, per Damon Martin of MMA Fighting.
A Del Rio win would be a significant upset, but he believes he can defeat the UFC Hall of Famer and put an end to Ortiz' illustrious career.
