A fight that was originally scheduled to take place at UFC Fight Night 18 in Tennessee has been rescheduled for the promotion’s upcoming event on Sept. 16 in Oklahoma City, Okla. Steve Steinbeiss and Ryan Jensen have agreed to try it again at UFC Fight Night 19 at the Cox Convention Center. Sources close to the fighters confirmed the bout to MMAWeekly.com on Wednesday.

The original bout was called off on the day of weigh-ins “due to a medical approval issue regarding (Ryan) Jensen,” stated UFC officials at the time. Independent sources confirmed to MMAWeekly.com that the alleged medical issue stemmed 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).”

Steinbeiss (4-2) will be making his promotional debut at UFC Fight Night 19, looking to erase the memories of a split decision loss to Carmelo Marrero in his last fight under the WEC banner.

Also coming off of a loss, Jensen will make his second start for the UFC, having lost to Wilson Gouveia via armbar last September at UFC Fight Night 15 in Omaha, Neb.

The two will try it again as part of the undercard at the recently announced UFC Fight Night 19, which features Nate Diaz against Melvin Guillard and Roger Huerta fighting Gray Maynard.
