It was fighters who had roots in the Lion's Den that were the original champions in three of the UFC's first four weight divisions. Ken Shamrock was the original UFC superfight champion in 1995, beating Dan Severn, which became the UFC heavyweight championship. Frank Shamrock was the first UFC middleweight champion in 1997, beating Olympic gold medal winning wrestler Kevin Jackson, which is now the UFC light heavyweight championship. Jens Pulver, who trained briefly at the Lion's Den in 1999 before joining Bob Shamrock's "Shamrock 2000" MMA gym and then moving on to MFS, beat Caol Uno to become the first UFC bantamweight champion in 2001, which is now the UFC lightweight championship. Mikey Burnett lost a close split decision to Pat Miletich for the creation of the UFC lightweight championship in 1999, which is today's welterweight title.
