GREAT FALLS, Mont. — Wrestling star Mike Zadick said disciplinary action against him by the U.S. Anti-Doping Agency was prompted by a procedural mistake in the documentation process.

The anti-drug agency said Friday that the Great Falls athlete tested positive for the drug triamcinolone acetonide at the recent Pan Am Championships.

"I have had an injury and was given the drug Kenalog from my physician to help the healing process," Zadick said Saturday in Colorado Springs. "The proper procedure is to fill out a TUE (Therapeutic Use Exemption). I was legally able to take the drug, but it had to be documented properly by filling out the TUE first. I have been educated about the proper requirements now and have learned from the situation."

The 29-year-old Zadick is an assistant wrestling coach at Iowa, his alma mater. He is currently working out at the U.S. Olympic Training Center in Colorado Springs in anticipation of earning a berth in the Olympics.
