The Washington Capitals and Philadelphia Flyers swapped defensemen on Friday, with Matt Niskanen joining Philadelphia and Radko Gudas going to Washington.

Niskanen was part of the Capitals' run to a Stanley Cup title in 2018, but his productivity dipped last season, as he had his fewest points (25) since 2012-13 while his per-game time on ice was his lowest in five seasons in Washington.
