The Flyers added depth to their blue line, acquiring defenseman Danny Syvret from the Edmonton Oilers in exchange for forward Ryan Potulny.
Syvret, 22, had two goals and 18 assists with 43 penalty minutes in 63 regular-season games for Springfield and Hershey Bears, of the American Hockey League, this season.
"Danny is a puck-moving defenseman that sees the ice well and will improve our depth," general manager Paul Holmgren said in a statement. "He had some success playing with Jeff Carter and Mike Richards at the 2005 World Junior Championship as a member of the Team Canada.
"Ryan was a good player for our organization, but this was a deal based on a need, as we added depth to our defense."
Syvret has appeared in 26 regular-season NHL games in the 2005-06 and 2006-07 seasons, with an assist and 12 penalty minutes.
Potulny, 23, played in seven games for the Flyers this past season, but spent most of his time with the Phantoms. He had 21 goals and 26 assists with 51 penalty minutes in 58 regular-season games in the AHL.
