Jagr had 46 points (16 goals, 30 assists) in 82 games for the Panthers last season, his 23rd in the NHL, and became the second-leading scorer in League history (1,914 points) behind Wayne Gretzky (2,857).
He has played 1,711 NHL games, fourth in League history and 56 behind leader Gordie Howe.
Huberdeau was limited to 31 games last season because of an Achilles injury. But beginning in the 2014-15 season, when the Panthers acquired Jagr in a trade with the New Jersey Devils, Huberdeau played on a line with Jagr and Aleksander Barkov.
On Wednesday, Huberdeau credited Jagr for helping him and Barkov, and said his legendary work ethic influenced the Panthers' younger players.
"I remember when he came in, I wasn't sure what to expect with a player like Jagr, a legend," Huberdeau said. "Would he care about us, the young guys. But, he did. He helped us and he gave us confidence too.
"Me and Barkov, playing with him, he told us we were really good players and we had to play the way we can play and to our potential. He helped us with the work ethic too. At the end of practice, he would make us skate again. It's cool to see a guy that is 45 and he can still do that."
Though Huberdeau wonders what lies ahead for his former linemate, he is excited about his own 2017-18 season. He said he has fully recovered from his injury.
