A draft pick of the now defunct Ottawa Renegades of the Canadian Football League, for whom he never played a game, Idonije signed with the Cleveland Browns of the NFL as an undrafted free agent in 2003.

Idonije was born in Lagos, Nigeria and immigrated with his family to Brandon, Manitoba, Canada, when he was four years old.

[4] Idonije was not invited to the NFL Combine, but appeared on his own to distribute tapes of his years at University of Manitoba.

[5] Idonije was subsequently signed to the Chicago Bears' practice squad for the final six weeks of the season.

[7] In 2006, Idonije became a restricted free agent and the Buffalo Bills attempted to sign him, but the Bears retained him by matching their offer.

[8] In 2011, in week 15 against the Seattle Seahawks, Idonije scored his first NFL touchdown after a fumble recovery in the end zone after Tarvaris Jackson had the ball stripped by Julius Peppers.

In the second game of the preseason against the Washington Redskins, Idonije recorded 2½ sacks on rookie and Heisman Trophy winner Robert Griffin III.

[10] Idonije ended the season with 40 tackles, 7.5 sacks, and a forced fumble, and he was later named to the USA Today All-Joe Team.

Idonije brought on writer Ron Marz and artist Bart Sears to complete the project.

Idonije also created Sports Heroes' showcasing athletes through comic artistry, and Athlitacomics became an NFLPA licensee.

[21] Idonije launched his DreamKidz Love book series to promote social and emotional awareness for children.
