Nigeria stripped of African, National U-20 Mixed 4x100m record 

World Athletics has stripped Nigeria  of the African and national under-20 records in the mixed 4x100m relay after the team was disqualified at the  U-20 Championships in Oregon, USA  for using unauthorised spikes.

The quartet of Tejiri Godwin, Chigozie Rosemary Nwankwo, Perfect Faye and Miracle Ezechukwu clocked 41.77 seconds to finish fourth in the final in Eugene, Oregon.

The performance initially stood as both an African and Nigerian U-20 record. Officials later ruled that Faye’s spikes were not on the World Athletics approved list, resulting in the disqualification and the erasure of the mark.

The decision came shortly after the race, in which Ezechukwu produced a strong 9.89-second anchor leg to lift the team from seventh place into fourth.

Italy won gold in a world under-20 record of 41.21 seconds, followed by Great Britain (41.38) and the United States (41.39). 

The disqualification means Nigeria loses both the continental and national junior records set in the event.
