In a call to the Flyers, the trainer was told to put Lindros on a plane that was returning to Philadelphia with injured teammate Mark Recchi. But Jones insisted that Lindros be taken to a nearby hospital and it was discovered Lindros had a collapsed lung caused by internal bleeding of his chest wall. Lindros' father wrote the Flyers a letter in which he stated that if the trainer had followed team orders, Eric would be dead, a statement supported by the doctors who treated him in Nashville. The 1999–2000 season would be Lindros' last as a Flyer. Having suffered his second concussion of the season (fourth overall) in March, Lindros criticized the team's trainers for failing to diagnose a concussion as he played with symptoms following a hit he suffered in a game against the Boston Bruins two weeks prior. Clarke then stripped Lindros of the captaincy for his actions. Lindros sat out the remainder of the regular season and suffered another concussion while rehabilitating for a return to the lineup. Lindros ultimately returned for Game 6 of the Eastern Conference Finals against the New Jersey Devils; he scored the lone goal in a 2–1 Flyers loss. In Game 7 of the series, Lindros was coming over the blue line with his head down, when Devils defenseman Scott Stevens lowered his shoulder into Lindros knocking him unconscious and suffering yet another concussion. He was able to get off the ice with help from teammates. The Flyers lost Game 7, 2–1 and the series despite leading three games to one, and Lindros became a restricted free agent during the off-season. He refused to accept a two-way qualifying offer with a minor league provision from the Flyers, who still owned his rights. After Lindros was cleared to play in December, the Flyers refused to deal his rights to the Toronto Maple Leafs, as he preferred, and Lindros sat out the entire 2000–01 season. Bobby Clarke eventually traded Lindros to the New York Rangers on August 20, 2001, in exchange for Jan Hlaváč, Kim Johnsson, Pavel Brendl and a 2003 third-round draft choice (Štefan Ružička). The Rangers would also receive a 2003 first-round draft pick if Lindros were to suffer a concussion in the pre-season or the first 50 games of the regular season, and did not return to action for at least 12 months. In 2001–02, Lindros averaged a little over a point a game with 37 goals and 36 assists for 73 points in 72 games.
