EUGENE, Ore. (AP) — Banned runner Shelby Houlihan saw her chances of competing at the U.S. Olympic trials diminish when the country’s Olympic committee said it would follow all antidoping rules and USA Track and Field received long-awaited official notice of her suspension. The developments wrapped up a whirlwind day that began with USATF saying it would not bar the American record-holder at 1,500 and 5,000 meters from the preliminary heats Friday. The USATF said it felt comfortable taking Houlihan off the start lists because it had received notice from the Athletics Integrity Unit. Houlihan received a four-year ban for testing positive for trace amounts of the performance enhancer nandrolone. She blamed her positive test on a pork burrito she ate before a test in December.
