UFC 22

The event was headlined by a Light Heavyweight Championship bout between Frank Shamrock and Tito Ortiz.

Shamrock would begin his short lived semi-retirement after this bout, citing a lack of competition.

30 seconds into Round 1, Kohler feigned a takedown attempt, only to land an explosive right cross.

Steve Judson was knocked out instantly, and suffered a deep gash to his chin at the point of impact.

Remaining unconscious and showing signs of having difficulty breathing, referees immediately signaled to the medical staff who administered oxygen treatment to Judson, who was taken out via stretcher to the local hospital.
