Flyers chairman Ed Snider has recently completed treatment for cancer, sources have told CSN's John Clark.
The specific form of cancer has not been disclosed, but according to Comcast-Spectacor spokesman Ike Richman, it's not life threatening. Snider is doing well, and his condition has not affected his ability to run the organization.
Snider was treated and released from Fox Chase Cancer Center.
Thursday night Snider told CSNPhilly.com's Tim Panaccio that he feels "great."
Snider, 81, founded the Flyers in 1966. He was the galvanizing force behind the construction of the Spectrum, which he took over in 1971, and three years later he created the management company Spectacor to oversee the team and the building.
Spectacor merged with Comcast in 1996 and became Comcast-Spectacor.
Snider was elected to the Hockey Hall of Fame in 1988, and he currently serves on the NHL's executive committee.
In 2011, he was elected to the U.S. Hockey Hall of Fame.
A philanthropist, he created the Ed Snider Youth Hockey Foundation in 2005 for underprivileged youth in Philadelphia.
Snider calls it the most “meaningful” accomplishment of his life. The ESYHF provides inner-city kids with a safe shelter that serves as a learning environment teaching kids life's lesson through hockey.
Though he frequently vacations to his home in Southern California, Snider has refused to retire.
Most of his close friends say he won’t retire until the Flyers win a third Stanley Cup.
