Nneka and Chiney Ogwumike and Elizabeth Williams filed an appeal to the Court of Arbitration for Sport on Friday, asking it to rule on FIBA's decision on their statuses to compete for the Nigerian national team in the Tokyo Olympics, according to ESPN's Ramona Shelburne.
The organization reportedly denied Nneka and Williams's applications to play for their native country while Chiney's was approved as a naturalized player—only one is allowed per roster—according to ESPN. Meanwhile, the third sister, Erica Ogwumike, is fully cleared.
FIBA's reason for denying Nneka was due to her "substantial involvement" with Team USA for more than a decade, according to ESPN's Shelburne and Mechelle Voepel.
