San Jose Lasers and Colorado Xplosion Henderson began her professional career playing for the San Jose Lasers and Colorado Xplosion. She signed a replacement contract with the Colorado Xplosion in December 1996.
Houston Comets Henderson spent the
1997 season on the Houston Comets' developmental squad as a
shooting guard. She never played in an actual game for the team during the season and was released shortly after the 1997 season ended. Henderson would finally get her time on the court as an active WNBA player when she played her debut game on May 28, 2001. On that day, the Comets lost their season-opening game to the
Los Angeles Sparks in a very close battle 66–63, with Henderson recording 4 rebounds and 3 assists (but no points). Although the Comets lost their first game, they would go on a 9-game win streak from May 31 to June 27 and have a 9–1 record in 10 games. The last half of the team's season was not as successful, as they would lose 12 of their final 22 games and end the season at 19–13. Henderson played in 23 games for the team (winning 14 out of 23 games) and averaged 1.1 points, 0.9 rebounds and 1.0 assists per game. The Comets made the playoffs but were swept in the Western Conference First Round by the Sparks. Henderson was waived by the Comets on May 22, 2002, 5 days before the 2002 season started. She would not play in the WNBA again after being waived by the Comets. Thus, her final game ever was Game 2 of the aforementioned 2001 first round series against the Sparks on August 20, 2001. The Comets lost the game 70–58 with Henderson only playing for 1 minute and recording no stats.
