The affidavit unsealed last week alleges that a check for $1,782 from Parmley, along with other funds, were deposited into one of Mitchell's account in late 2009.
Mitchell, 57, and his two sons are among nine people named in an 81-count federal indictment unsealed in September. All are accused of participating in an illegal gambling business that operated poker games, took sports wagers, used an illegal gambling website and laundered illegal gambling proceeds.
Mitchell, who prosecutors allege was the leader of the operation, has pleaded not guilty.
Authorities say Mitchell has been under investigation for more than two years as state and federal grand juries looked into the alleged criminal activity, as well as the November 2010 beating death of his wife, Julie Mitchell, whose body was found inside the couple's Oklahoma City home. Her death remains unsolved.
According to the NCAA website, the organization's rules "prohibit student-athletes, and athletics department, conference office, and NCAA national office employees from wagering on intercollegiate, amateur, and professional sports in which the association conducts championships."
