- Runner took silver at world indoor championships
- Houlihan blamed four-year ban on tainted pork
American runner Shelby Houlihan returned to the big stage after a much-debated four-year doping ban and won a silver medal in the 3000m at the world indoor championships.
The US record holder at 1500m sat out the Paris Olympics after her ban. The 32-year-old said she was flooded with a range of emotions after her second-place finish on Saturday behind Ethiopia’s Freweyni Hailu, who won gold.
