UFC 109: Relentless

A Heavyweight main event between UFC Hall of Famers Randy Couture and Mark Coleman headlined the card, a matchup originally scheduled for UFC 17 in 1998 before being canceled due to a Couture injury. Their eventual meeting carried historic weight as the first UFC main event featuring two Hall of Famers. The co main event saw Chael Sonnen defeat Nate Marquardt, positioning Sonnen for a title shot against Anderson Silva later that year.
