Count Jaromir Jagr among the names that will be available on the open market on July 1.
TSN Hockey Insider Darren Dreger reported via Twitter on Monday that while the 40-year-old winger enjoyed his stint with the Philadelphia Flyers last season, he plans on testing free agency.
Jagr, who scored 19 goals and 54 points in 73 games last season, played the previous three years in Russia and helped lead the Penguins to two Stanley Cup titles in the 1990s. He also played for the New York Rangers and Washington Capitals.
A Czech native, Jagr won an Olympic gold medal in 1998 and a bronze in 2006. He also won two Ice Hockey World Championships in 2005 and 2010.
He made $3.3 million last season with the Flyers.
