The source, who requested anonymity because the hire is not yet official, said the 39-year-old Webster will be the third and final assistant coach hired by Martin.
The Vols still have openings for graduate assistant coaches and a director of basketball operations.
Webster, like Martin and UT assistant coaches Jon Harris and Kent Williams, has a strong background as a player, earning All-Big Ten honors three times while playing point guard at Wisconsin from 1991-94.
Webster was a three-time team captain for the Badgers and set school records for assists in a season (179 in 1992-93) and single-season 3-point shooting percentage (.490 in 1991-92).
Webster’s coaching background is as follows:
n 1997-98, Verona (Wis.) High School assistant
n 1998-99, University of Wisconsin-Parkside, assistant
n 2001-03 Ball State, assistant
n 2003-04 Purdue, assistant
n 2004-07 Illinois, assistant
n 2007-09 Kentucky, assistant
n 2009-10 DePaul assistant/interim head coach
n 2010-11 Nebraska assistant
Webster in September 2009 was ranked one of the top 50 basketball assistant coaches in the nation by HoopScoopOnline.com and has recruited Midwest hotbed cities Chicago, Milwaukee, Detroit and Indianapolis.
Webster attended Thornton High School in Harvey, Ill., near Chicago, and in 1992 the Chicago Sun-Times ranked him as the sixth-best point guard in Chicago-area high school history.
UT coordinator of video scouting Houston Fancher, who was Appalachian State’s head coach from 2000-2009 before joining the Vols, has remained on staff since Martin was named coach on March 27.
Fancher is believed to be a candidate for the vacant director of basketball operations position.
