UFC 22: Only One Can Be Champion
Sept. 24, 1999 – Lake Charles (La.) Civic Center
Frank Shamrock walked away from the UFC and his light heavyweight title after a scintillating title defense over Tito Ortiz.
The brash, young Ortiz battled Shamrock into the fourth round before succumbing to punches late in the fourth round.
Shamrock later vacated the title, citing a lack of competition. He finished his career by posting a 4-3 record in Strikeforce, K-1, WEC and EliteXC.
