Women's 400 champ Salwa Eid Naser could miss Olympics

MONACO -- Women's 400-meter world champion Salwa Eid Naser faces a new legal case that could see her banned before the Tokyo Olympics.

Track and field's Athletics Integrity Unit says it has appealed to the Court of Arbitration for Sport against a disciplinary ruling last month that closed a case against Naser. She had been charged with breaking anti-doping rules by missed doping tests and failing to update details of how she could be found by sample collection officials.

The charges were dismissed on a technicality. It meant the Nigeria-born Bahraini kept her title from the 2019 world championships and was cleared to compete in Tokyo next year.
