Streit will have surgery Tuesday to repair a pubic plate detachment and will miss six weeks, Flyers general manager Ron Hextall said Saturday. He was placed on long-term injured reserve. Umberger was placed on injured reserve because of a lower-body injury.
The 37-year-old Streit is second on the Flyers with nine points and with 22:45 of ice time per game. Prior to this injury he had missed one game in three seasons with the Flyers.
"He's a big factor for us in terms of his leadership," Philadelphia coach Dave Hakstol said. "He's a very quiet leader but extremely well respected in our room. Just the consummate professional who every day does the right thing. It leaves a gap that others have to fill and it's an opportunity for others to step into as well."
