Rangers president and general manager Glen Sather is expected to undergo surgery for prostate cancer Thursday in New York, according to three sources close to Sather. He is to be hospitalized for a few days and resume his normal duties soon, the sources said. Assistant general manager Jeff Gorton was representing the team at the NHL general managers meetings in Toronto Wednesday, the team confirmed. Sather, 69, was not available for comment. "Almost all of Glen's business is done on the phone anyway," a source said. "He just doesn't want anybody to make a fuss over him." Sather, who was inducted into the hockey Hall of Fame in 1997, is the franchise's 12th president and 10th general manager since June 1, 2000. Before that, he was the general manager in Edmonton, where the Oilers blossomed into a dynasty and won five Stanley Cups. He ranks 16th on the NHL's all-time coaching list with 497 victories. Gorton, 43, is in his second season as an assistant general manager, overseeing day-to-day business in hockey operations, including salary cap and collective bargaining issues and administration of player contracts.
