An exterminator couldn’t out the rat in the Wake Forest broadcast booth.

Former Demon Deacons assistant football coach and radio colorman Tommy Elrod provided, or attempted to provide, confidential game-plan information to other teams on multiple occasions since 2014, a Wake Forest investigation has found.

The school’s investigation was sparked from a Nov. 12 game against Louisville, after which members of the team found materials left behind by Louisville signaling the Cardinals had Wake Forest’s game-plan preparation. Included in the documents were Wake Forest plays that had not been run before.

On Tuesday, Wake Forest released a statement saying it had found Elrod, an alumnus of Wake Forest and member of its football team from 1993-97, had been the security breach. He was fired immediately from Wake Forest IMG Radio Network, on which he had provided color commentary since 2013, and his presence had been scrubbed from the school’s athletics page. Elrod, who coached the Demon Deacons for 11 seasons in various positions, also was banned from Wake Forest facilities for his role in what is being dubbed as “WakeyLeaks.”

“I have known Tommy Elrod since his days as a player on our football team,” Wake Forest athletics director Ron Wellman said in a statement.”I’m deeply disappointed that he would act against Wake Forest, our football team and our fans in such a harmful manner by compromising confidential game preparation information. It is a relief that the team can move forward without his action further undermining the positive strides [head coach] Dave Clawson, his staff and the team have made.”

Wake Forest, 6-6, will play No. 24 Temple in the Military Bowl on Dec. 27.

“It’s incomprehensible that a former Wake Forest student-athlete, graduate-assistant, full-time football coach, and current radio analyst for the school, would betray his alma mater,” Clawson said in a statement.
