ORLANDO, Fla. — The Amateur Athletic Union is set to announce changes to its policies as a sex abuse investigation centered on its former president progresses in Tennessee.

The AAU has called a news conference for Wednesday afternoon at its headquarters near Orlando, Fla. It's expected to announce the establishment of two tasks forces that will look at the organization's internal protocols and policies for athlete safety.

Memphis police said Monday that investigators are trying to follow up allegations that ex-AAU president Robert "Bobby" Dodd molested children 30 years ago, but they have not received a formal victim complaint.

Investigators have received information from the AAU about accusations, but are not disclosing whether they are investigating one or several.

The 63-year-old Dodd retired last month. The AAU says he has colon cancer.
