MIAMI — David Montgomery, the Phillies' president since 1997, underwent surgery Monday to remove cancer from his right jaw bone, the team said Tuesday in a statement.
Montgomery will remain hospitalized at Thomas Jefferson University Hospital for about a week. He turns 68 in June, and is in his 44th season with the Phillies.
"Although [this was] significant surgery, David has been advised that the success rate in situations such as his is very high and complications are not expected," the team's statement said.
The Phillies expect Montgomery to require some recuperation time at home following his hospital stay.
Montgomery, a Philadelphia native and University of Pennsylvania graduate, is the general partner and public face of the Phillies' ownership group. He was installed into that role in 1997. He started in the organization in 1971 as a ticket sales representative.
Phillies manager Ryne Sandberg addressed his players at Marlins Park prior to Tuesday's game. "You could hear a pin drop in the room," Sandberg said, "and a lot of players came up with questions about him." Sandberg said the team's thoughts were with Montgomery.
"He's a guy who, in a lot of ways, is our biggest fan," Sandberg said. "From my experience here the last four years, he's the guy who sets the tone as far as it being a family-oriented organization — first-class, the right way. He's the leader of the organization. ... It all starts with David Montgomery."
Last week, Montgomery was appointed to a seven-man search committee for Bud Selig's successor as Major League Baseball commissioner.
