Niedermayer was drafted fifth overall by the Florida Panthers in the 1993 NHL Entry Draft. At the time, he was playing for the Medicine Hat Tigers of the Western Hockey League (WHL). He began his NHL career immediately following his draft, without playing a game in the minors. During the 1995–96 season, he set career highs in goals, assists and points in the regular season. In the 1996 Stanley Cup playoffs, the Panthers went on an improbable playoff drive to the Stanley Cup Finals before being swept in four games by the Colorado Avalanche. Niedermayer was hurt by concussions in the next years and was never able to achieve the same level of scoring ability again. His NHL role soon turned into a defensive forward.
