Tito Ortiz's fighting career is over, but it appears the UFC Hall of Famer is committed to a new cause.
Ortiz recently suffered a decision loss in his retirement fight at UFC 148, and afterward, he learned opponent Forrest Griffin was the latest MMA fighter who was granted a therapeutic-use exemption for testosterone-replacement therapy.
On Monday Ortiz told AXS TV's "Inside MMA" it's a problem "that has to be nipped in the bud."
