A middleweight bout between Arizona Combat Sports fighter
In a statement received by MMAWeekly.com, UFC officials said the fight was off "due to a medical approval issue regarding (Ryan) Jensen."
Questions about the fight were raised during the weigh-ins on Tuesday when Jensen and Steinbeiss did not come out with their fellow athletes during the customary event. They did appear about 15 to 20 minutes later with both fighters weighing in at 186 pounds.
Independent sources have confirmed to MMAWeekly.com that the alleged medical issue stems from Jensen's use of Adderall, which is not allowed under standard athletic commission rules.
According to drugs.com, "Adderall is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.
"Adderall is used to treat narcolepsy and attention deficit hyperactivity disorder (ADHD)."
According to sources, Jensen disclosed his use of the drug to the commission and the bout was held up pending further approval. Obviously, the commission decided to scrap the bout all together, and Jensen vs. Steinbeiss will no longer happen ... at least in Nashville, Tenn., Wednesday night.
