Nigerian Sprinter, Blessing Okagbare has been handed an extra one-year ban for additional doping violations.
The Athletics Integrity Unit charged her with evading sample collection and tampering or attempted tampering with the doping control process.
In February, Okagbare was handed her original ban for multiple breaches of anti-doping rules.
As a result of her additional ban, Nigeria has lost its potential qualification place in the women’s 4x100m relay at July’s World Championships in Oregon.
