Lageman's playing career ended on the first game of the 1998 season in Chicago. Although the Jaguars won on a last second touchdown pass from Mark Brunell to Jimmy Smith, they lost Lageman to a torn muscle in his arm. He never played again.
During his time in Jacksonville, Lageman, an avid hunter and fisherman, began his broadcasting career with a radio show titled "The Outdoors Show" along with Captain Kevin Faver and Captain Kirk Waltz. After his playing career, Lageman continued his broadcasting career as a football color analyst on Fox television.
By 2001, "The Outdoors Show" had moved from an all-sports station (WBWL-AM) to a 50,000 watt news-talk station (WOKV) and soon after, Lageman joined the play-by-play man Brian Sexton in the booth of the Jaguars Radio Network as the color analyst. He also serves as co-host of the weekly "Jaguars This Week" radio show along with Sexton, Jaguars.com senior writer John Oehser and former Jaguars teammate Tony Boselli, and is a castmember of the weekly television program, Jaguars All Access. Lageman lives in Jacksonville with his wife, Tera Lageman, and their children Taylor and Dylan.
