Tennessee announced the resignation of senior associate athletic director Mike Vollmar on Wednesday night.
The move comes during new athletic director John Currie's second week on the job.
Currie's predecessor, Dave Hart, brought Vollmar to Knoxville in 2013 to be responsible for oversight of the Tennessee football program.
Vollmar came to Tennessee from Michigan, where he was associate athletic director for football.
He has also worked in similar roles at Alabama and Michigan State.
In a statement from Tennessee, Vollmar thanked Hart and reflected on his time on campus.
"My family and I have really enjoyed this community and everything it stands for," Vollmar said in the release. "This athletic department is tremendous from top to bottom and is blessed with great people. I have a great working relationship with Butch Jones and his staff and look forward to watching their continued ascent.
"We are proud of many things we were able to accomplish together including the enhancements made in the Anderson Training Center and the many other worthwhile projects that impacted all of our student-athletes."
Currie, who spent eight years as the athletic director at Kansas State, is expected to make hires for senior posts in the athletic department in the coming weeks and months.
Tennessee's executive senior associate athletic director Jon Gilbert left in January to become the athletic director at Southern Mississippi.
Chris Fuller, who spent 12 years at Tennessee in a variety of athletic department leadership roles, took a position as the deputy athletic director for external operations at Syracuse in November.
Hart's retirement was announced in August.
Vollmar said in the university release that he met with Currie Wednesday to inform him of his intent to "pursue other opportunities."
"I have enjoyed getting to know John the last couple of weeks and have no doubt he will do a great job leading the athletics department," Vollmar said in the release. "It is my hope that every student-athlete at Tennessee achieves great success on and off the field."
Currie has been active on campus and in the community during his first two weeks on the job and has said multiple times that listening is his first priority for his first days in the athletic director role.
"Mike and I had a good meeting Wednesday, during which he informed me of his plans to resign to pursue other opportunities," Currie said in the release. "I appreciate Mike's impact on the revitalization of the Tennessee football program and his service as a member of the athletics executive staff."
