Mike Tyson donating paycheck from Roy Jones Jr. fight to charity

Mike Tyson has dispelled the idea that he's looking to get rich off his upcoming exhibition match against Roy Jones Jr.

During an appearance on "TMZ Live" on Thursday, the 54-year-old Tyson said he'll be donating his cut from the fight to charity.

"It's going to be for various charities, so nobody's gonna have to worry about me getting rich or being jealous and saying I'm doing this for money," Tyson said. "I'm not getting anything and I just feel good doing this because I can."

Tyson is taking the fight seriously, though, and won't be going easy on Jones.

"Anybody who knows me, I don't know how to (take my foot off the gas)," he said. "I just know one way of fighting and that's just what it is."

The eight-round match will reportedly take place in California on Sept. 12.
