Colleagues at Genesis Communications are mourning the sudden death of Keith Lippert, who was stricken Friday night as he prepared to do play-by-play of a high school football game in Melbourne, FL. Lippert, who was 43, and two other staffers from WIXC-AM had unloaded their gear and were heading to the press box to set up. But as Lippert started to open the door, he collapsed. After treatment at the scene, he was transported to a nearby hospital where he was pronounced dead. Along with his play-by-play work, Lippert had hosted the "Friday Night Locker Room with Keith Lippert" show on WIXC. A memorial service is scheduled for Saturday.
