The Flyers waived center Glen Metropolit and defenseman Ossi Vaananen on Thursday to clear salary cap space for Daniel Briere's impending return on Friday, according to an Associated Press report. Briere has missed the past 35 games and played in only nine games this season because of surgery on his abdomen and groin. The Flyers needed to dump about $2.5 million in cap space to fit Briere on the roster, and will likely need to make at least one more move.
