Details were not released on the status of Webster's contract or if it has been adjusted.
Webster and Martin played against each other as collegians, with Webster starring at Wisconsin and Martin at Purdue. The two then coached alongside each other in 2003-04 when Purdue coach Gene Keady added Webster to a coaching staff already featuring Martin.
The two were reunited on April 5, 2011 when Martin hired Webster as his top assistant at UT.
Webster's base salary prior to the promotion had been $193,000, the highest salary for Martin's three assistants. The highest paid assistant on the women's basketball team, Kyra Elzy, was earning $225,000.
"This is about the work that Tracy has put in," Martin said in a UT release. "He's a tireless worker, and he's driven to see this program be successful. His efforts to develop our current players, along with his efforts in recruiting, deserve to be rewarded."
Webster primarily works with Tennessee's guards and is Martin's lead recruiter.
