According to TSN's Darren Dreger, Coburn is available and the Flyers might be looking for a forward in exchange.
The Edmonton Oilers and Carolina Hurricanes are searching for help on the blueline and are believed to have some interest in Coburn.
In 33 games with the Flyers this past season, Coburn registered one goal, four assists and 41 penalty minutes.
The Flyers have approximately $9 million in available cap space, which includes Chris Pronger being on LTIR, but GM Paul Holmgren is looking to create additional space.
Philadelphia has already committed to buying out goalie Ilya Bryzgalov and center Danny Briere.
Coburn has a limited no-trade clause and has some say in where he might end up, should the Flyers pull the trigger on a trade.
