Nigeria's 4x400m quartet was disqualified
Nigeria's Olympic humiliation was completed Saturday evening when her 4x400m women's quartet was disqualified in the final of the race, which was won by the US.
But even without the disqualification, the Nigerian girls were never in medals' contention and crossed the finish line in seventh spot.
Their flop means that Nigeria officially finished competing at London 2012 without winning a medal of any colour - as was the case at Moscow'80 and Seoul'88.
Finishing second behind the Americans was Russia while Jamaica won the bronze medal.
