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 of the American Hockey League last 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."
Syvret has appeared in 26 regular-season NHL games over two seasons, with an assist and 12 penalty minutes. In February, he was part of an AHL trade that involved Grant Potulny, Ryan's older brother.
Ryan Potulny, 23, played in seven games for the Flyers last 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.
Potulny registered 14 points and 26 penalty minutes in 44 regular-season games for the Flyers.
"Ryan was a good player for our organization," Holmgren said, "but this was a deal based on a need, as we added depth to our defense."
