Davis joined
ESPN Radio in January 1992. Davis was on
The Tony Kornheiser Show between January 5, 1998, and March 26, 2004. When Davis reported the sports updates, the host,
Tony Kornheiser, often interrupted Davis' reports with his own comments. Initially, Davis was shocked and not amused. However, later on Davis developed a very good chemistry with Kornheiser, and he even started to add humorous comments within his report to amuse (or annoy) Kornheiser. Davis and Kornheiser talking back and forth in this way prompted Kornheiser to say that The Duke was the glue of the show. Throughout his tenure, Davis provided Sportcenter updates on ESPN Radio. Davis has also appeared on other programs. Sometimes, he made comments on
Extra Point. He supplied his voice during the Week 10 edition of ''
Mike and Mike's
"Stone Cold Lead Pipe Locks" on November 7, 2008. On December 21, 2011, on Mike and Mike'', it was announced that Davis was retiring from ESPN Radio, effective December 23. ==Personal life==
