It will be the second NHL game for the 33-year-old Zepp, who was recalled from Lehigh Valley of the American Hockey League on Sunday after goaltender Steve Mason sustained a lower-body injury Saturday against the Boston Bruins.
Zepp made 25 saves in the Flyers' 4-3 win Dec. 21 against the Winnipeg Jets. According to Hockey-Reference.com, Zepp became the oldest player since the 1926-27 season to win his NHL debut.
"I liked his game in Winnipeg, liked his energy," Flyers coach Craig Berube said. "Going to need energy tonight. That's all. Just a decision I made."
