Antone Davis, Tennessee's coordinator of the Vol For Life program, has resigned.

Sources that spoke with GoVols247 Wednesday morning said Davis has submitted a letter of resignation. The bio page for Davis on UTSports.com has since been wiped. Davis had been VFL Coordinator since 2012.

Tennessee confirmed the news Wednesday afternoon in a press release, saying "Davis is resigning his position as VFL Coordinator with the UT football program to pursue personal business opportunities."

Sources told GoVols247 that Davis believed he was part of a hostile work environment. He resigned to pursue job opportunities outside of athletics.

This season, according to sources, he was made to drive to and from away games if he wanted to travel, after flying on team charters in the past. Davis was only allowed to travel, sources said, if he supplied his own travel arrangements.

Additionally, job responsibilities were continually being taken away from Davis, leading to his resignation.

Tennessee on Wednesday did not immediately respond to GoVols247's request for comment on the Davis resignation or the reasons behind it.

News of the resignation surfaced after head coach Butch Jones held his weekly Wednesday press conference.

“We appreciate Antone’s work for the University of Tennessee and our football program,” Tennessee athletic director John Currie said in a statement.

“He had an outstanding career here as a student-athlete and then returned more than 20 years later to impact the lives of young men who were following in his footsteps. We wish him all the best in his future endeavors.”

Dakota Davis, the son of Antone Davis, plays football at Chattanooga, listed on the Mocs’ roster as a 6-foot-3, 280-pound freshman offensive lineman.

A former two-time first-team All-SEC Tennessee offensive tackle, Antone Davis took over for Andre Lott, who originally ran the program started by former coach Derek Dooley.

Davis, at Tennessee from 1986-90, was the eighth overall pick in the 1991 NFL draft, the start of a seven-year pro career.
