TULSA — Tulsa Washington High School head coach Antwain Jimmerson resigned Monday afternoon after 10 seasons.

Jimmerson led the Hornets to a Class 5A state title in 2008, but he had a rocky 2009.

He was suspended indefinitely from his coaching duties and removed as athletic director in October after it was determined that more than 40 Washington student-athletes were ineligible to play.

The football team forfeited three games, including a 90-0 victory over Miami on Oct. 3.

The forfeits left the Hornets out of the 2009 playoffs.

It marked the first time in Jimmerson’s tenure at Washington that the Hornets failed to make the playoffs.

A call to Jimmerson’s residence wasn’t immediately returned Monday night.

Tulsa Public School athletic director Stephanie Spring said the head coaching position will be posted by Tuesday morning.

“He felt like it was in his best interest and of Booker T. (to resign) and you’ve got to respect that decision,” Tulsa Public Schools athletic director Stephanie Spring told the Tulsa World. “I was (TPS) AD when we hired him. I appreciate all of the things he did for the program. We wish him nothing but the best.”

Jimmerson has not resigned as a teacher at Booker T. Washington, Spring said.
