"I want to get completely healthy and then see what happens," Jagr said in April. "I don't want to retire yet. I can always play here. My plan is just to get healthy first and then see how far I can go."
Jagr told The New York Times then he had not ruled out returning to play in the NHL.
Jagr was voted one of the 100 Greatest NHL Players presented by Molson Canadian. He has 1,155 assists, 14 behind Ray Bourque for fourth in NHL history; Gretzky leads with 1,963. Jagr is the all-time NHL leader with 135 game-winning goals.
Jagr won the Stanley Cup in 1991 and 1992 with the Pittsburgh Penguins, who selected him No. 5 in the 1990 NHL Draft. He won the Hart Trophy as the NHL's most valuable player in 1999, the Art Ross Trophy as scoring champion five times (1995, 1998-2001), and the Masterton Trophy for perseverance and dedication to hockey in 2016.
He played two seasons for Kladno before joining the Penguins for the 1990-91 NHL season. He also played in the NHL for the Washington Capitals, New York Rangers, Philadelphia Flyers, Boston Bruins, Dallas Stars, New Jersey Devils and Florida Panthers, and in the Kontinental Hockey League for Avangard Omsk.
