Bernard Hopkins says there is more on the line than two world titles when he takes on Beibut Shumenov in Washington on Saturday night.
The legendary 49-year-old will look to make history once again by extending his own record as the oldest world champion the sport has ever seen.
But the IBF light-heavyweight champion insists his legacy is there to be shot at when he takes on the WBA title holder this weekend.
"This is really a defence of my legacy - belts are nice, but they're nicer when you're younger and establishing a foundation," he said.
"My foundation was laid down years ago. You get what you put in most of the time and then you get the times where you have to fight for what you want.
"Enjoy and understand that this is history. I'm defending something bigger than a title. My legendary 20 plus year legacy is more important than anything around my waist.
"He's motivated to fight me, he said he's been dreaming of this all his life. Understand one thing, be careful what you wish for."
In a world title triple-header Shawn Porter makes a first defence of the IBF welterweight strap he took from Devon Alexander in December against New York veteran Paulie Malignaggi, while Peter 'Kid Chocolate' Quillin defends his WBO middleweight title against tough European Lucas Konecny.
