Underwood was selected by the Minnesota Vikings in the first round (29th overall) of the 1999 NFL Draft, after his stock rose with his pre-draft workouts. On Aug. 1, he signed a five-year, $5.3 million contract with a $1.7 million bonus. He walked out of training camp the next day, after the first practice and never returned. On August 13, he was waived and forfeited a $1.75 million bonus saying he could not resolve the conflict between playing football and serving his Christian faith. On March 10, 2000, he signed a two-year contract with the Dallas Cowboys. In January 2001, he tried to kill himself by running into traffic twice on a busy suburban highway.
