The 1999–2000 Philadelphia Flyers season was the Philadelphia Flyers' 33rd season in the National Hockey League (NHL). One of the most tumultuous seasons in franchise history, 1999–2000, actually started in July three months prior to the start of the regular season. In the span of a few days, longtime broadcaster Gene Hart died due to illness and defenseman Dmitri Tertyshny, coming off his rookie season, was fatally injured in a freak boating accident. The season itself was no better as head coach Roger Neilson was diagnosed with bone cancer, forcing him to step aside in February 2000 to undergo treatment. The team was left in the hands of interim coach Craig Ramsay for the rest of the season.
