Notable performances have come from Alabi, Agunbiade, Ogunkunle, and Commonwealth Games medallists Kate Oputa and Faith Obazuaye, who have showcased their class against emerging talents across various classifications.

Their presence has intensified the battle for podium finishes, with top seeds asserting dominance in their respective singles events.

The AIU announced in the June 2025 sanctions list on July 1 that 21-year-old quarter-miler Uko was found guilty of an anti-doping rule violation committed on June 5 2024. Her infraction falls under whereabouts failures, having missed three tests within a 12-month period.

The AIU confirmed that her period of ineligibility will run until 23 July 2026 and all results recorded from the date of the infraction have been officially disqualified.

Uko rose to fame after clinching three gold medals at the 2021 World U-20 Championships in Nairobi, winning the women’s 400 metres, 4x400m relay, and the mixed 4x400m relay.

Stephen Eloji (June 2028)

Sprinter and hurdler Stephen Eloji tested positive for dehydrochloromethyl-testosterone in an out-of-competition test in Nigeria on May 2, 2024 and has been handed a four-year ban by the AIU.

The 25-year-old was active in the American collegiate circuit, recording strong performances in the 110m hurdles and relay events as recently as April 2024, including at the Pepsi Florida Relays and Music City Challenge.

Ada Princess Bright (September 2027)

Ada Princess Bright is serving a four-year ineligibility period after testing positive for Metenolone during the National Athletics Trials held on July 6 2023 in Benin City.

She had an active season prior to her suspension, competing in national meets in Lagos, Uyo, and Benin, and earning a relay gold at the African U20 Championships in Ndola, Zambia.

Grace Nwokocha (August 2025)

Nwokocha is serving a three-year ban after testing positive for SARMS substances including Ostarine and Ligandrol during the 2022 Commonwealth Games in Birmingham.

The fallout was significant, as Nigeria was stripped of its women’s 4x100m relay gold medal at the Games. Prior to her suspension, she had qualified for the Tokyo Olympics, posted a personal best of 11.00s in the 100m, and reached the semi-finals in the 100m and 200m at the 2022 World Athletics Championships. She is ineligible to compete until 2 August 2025.

Yinka Ajayi (January 2030)

Ajayi, a 400m specialist and one-time Olympic representative, is currently serving an extended eight-year ban for multiple anti-doping violations.

The first sanction, issued after she tested positive for Metenolone in an out-of-competition test in Iowa, USA, led to a four-year ban starting in December 2021. However, further findings of tampering led to an additional four-year penalty in 2024, extending her suspension until January 25 2030.

Glory Okon (January 2026)

Glory Okon is serving a four-year ban for testing positive for Metenolone following an out-of-competition test conducted on December 2 2021 in Nigeria.

Blessing Okagbare (July 2031)

Once the face of Nigerian athletics, Okagbare is now serving a 10-year ban following multiple anti-doping rule violations. She tested positive for human growth hormone and EPO in an out-of-competition test in June 2021.

Her suspension came while competing at the Tokyo Olympics and was announced in February 2022. It was later extended by an additional year in June 2022 due to further breaches.

Divine Oduduru (February 2029)

Oduduru’s  career was derailed by anti-doping violations linked to the 2020 Tokyo Olympics. On October 12 2023, a Disciplinary Tribunal of the AIU imposed a six-year ban on Oduduru after he was found guilty of possessing and attempting to use prohibited substances and methods. The case stemmed from the wider investigation into Eric Lira, the first individual convicted under the US Rodchenkov Anti-Doping Act, who supplied banned substances to athletes, including Okagbare, ahead of the Tokyo Games.

Oduduru’s ban is effective from February 9, 2023 and will run until February 8, 2029.

Henry Azike (Lifetime ban)

Azike is one of two Nigerian athletes currently serving a lifetime ban after testing positive for Metenolone, an anabolic steroid. His case was classified as a second ADRV, automatically triggering a lifetime suspension from the sport.

Azike last competed in 2011, including at the Doha Amir Cup and Nigerian Championships in Calabar.

Vivian Chukwuemeka (Lifetime ban)

Two-time Olympian and African shot put record holder Vivian Chukwuemeka is serving a lifetime ban for a second doping offence after testing positive for Stanozolol at the 2012 National Championships in Calabar.

Invited players into the Super Eagles B camp ahead of the rescheduled African Nations Championship tournament are feeling the pressure of selection, three days into their training camp at the Remo Stars Stadium in Ikenne, Ogun State.

The eighth CHAN tournament is taking place in Kenya, Tanzania and Uganda between August 2 to 20.

Ahead of the tournament, head coach Eric Chelle had invited an initial 35 players to camp and they began training on Monday with 21 players.

Five more players arrived on Tuesday to take the number to 26 while 28 players trained on Wednesday morning with the rest expected before the end of the week.

Captain of the team through the qualifiers, Junior Nduka, spoke about the intensity of the sessions and the jostle to make the final squad.

“Everybody is under pressure but definitely the coaches want the best among the 35 players,” Nduka said.

River United and former Flying Eagles forward, Aniekeme Okon, also admitted the pressure.
