NORMAN — Oklahoma defensive lineman Amani Bledsoe has filed a lawsuit against the NCAA regarding a one-year suspension he was issued last season after failing a test for performance-enhancing drugs.

The civil lawsuit was filed Aug. 24 in Cleveland County and asks for the NCAA to lift Bledsoe’s suspension and restore one year of eligibility. The lawsuit also seeks reimbursement for court costs and attorney fees.

Court documents state Bledsoe’s problems began last year when he ran out of a whey protein supplement he had regularly used since his freshman or sophomore year of high school. The lawsuit states Bledsoe did not have a car and asked an unnamed OU teammate where he could buy more protein powder near the OU campus.

Per the lawsuit, the teammate told Bledsoe he had an unopened container of Inner Armour protein powder in his dorm. Bledsoe took one “very large” serving of powder mixed with water, and later purchased his own protein, from the brand Optimum Nutrition, according to the lawsuit.

On or around Oct. 5, 2016, Bledsoe and several other OU athletes submitted to random drug testing by the NCAA, which involved collecting two urine samples.
