It won't be as easy as it was in the old neighborhood. History indicates it is nearly impossible.

Of the 13 light heavyweight champions who challenged for the heavyweight title, only Michael Spinks was successful. And, unlike Jones, Spinks had the size of a heavyweight when he beat Larry Holmes in 1985.

Jones is a 9-5 favorite even though Ruiz outweighs him 226-193. Jones' only loss in 48 professional fights was a disputed disqualification.

The fight will be televised on pay-per-view beginning about 8:30 p.m.
