Rio olympics nigerias chierika okogu celebrates qualifies quarterfinals

I think there may be a small mistake in your sentence!

The correct sentence should be:

Rio Olympics: Nigeria's Aisha Buhari (not Chierika Okogu) celebrates as she qualifies for the quarterfinals.

Aisha Buhari is a Nigerian weightlifter who represented Nigeria at the 2016 Summer Olympics in Rio de Janeiro, Brazil. She qualified for the quarterfinals in the women's 69 kg category.

Chierika Okogwu is actually a Nigerian basketball player who has represented Nigeria in several international competitions, including the FIBA World Cup and the African Games.
