Pronger, who has four goals and 21 assists in 50 games this season for the Eastern Conference-leading Flyers, will have the fracture repaired by Dr. Tom Graham in Cleveland, General Manager Paul Holmgren said.
"Chris had a CT scan on his right hand on Sunday and a small fracture was discovered," he said. "Our doctors believe surgery is the best route to take with the injury."
The 36-year-old Pronger was hurt Feb. 24 against the New York Islanders when he took a shot off the hand. He has missed three games since then.
