Philadelphia general manager Paul Holmgren made the announcement Tuesday night before the Flyers played the Islanders.
Emery hadn't been playing well, and was pulled from Saturday's game against the Capitals after allowing five goals.
Holmgren said the injury played a part in Emery's slump.
"You know how hard he practices," Holmgren said. "He's been trying to fight through this, but couldn't practice the way he normally does, and his game suffered. He's a down young man, and feels he let his team down."
