The Flyers acquired Matt Niskanen from the Capitals for Radko Gudas on Friday in a one-for-one swap of defensemen that upgrades Philadelphia's blue line offense and gives Washington much needed salary-cap space.

Niskanen provides the Flyers with an offensive-minded, right-handed shot who can also help on the power play. Philadelphia is retaining 30% of Gudas' $3.35 million cap hit, which means Washington saves $3.405 million going into an offseason with several players in need of new contracts.

"We feel this move provides us with financial flexibility as we look for additional ways to strengthen our team," Capitals general manager Brian MacLellan said. "In addition, we are pleased to welcome Radko to our organization. Radko is a good defensive defenseman that plays a competitive, physical game."
