Matt Niskanen has decided to hit the open market on July 1.
Niskanen's agent, Neil Sheehy, tweeted on Thursday that the defenceman had spoken to the Pittsburgh Penguins and informed the team he would test the free agent market.
The 27-year-old scored 10 goals and added 36 assists for a career-high 46 points with the Pittsburgh Penguins last season. He added two goals and seven assists in 13 playoff games.
This past season marked the final year on a two-year pact he signed with the Penguins prior to the 2012-13 season worth an average annual value of $2.3 million.
Originally drafted by the Dallas Stars in the first round (28th overall) of the 2005 NHL Entry Draft, the Penguins acquired Niskanen in the same trade that brought James Neal to Pittsburgh. In 491 career games with the Penguins and Stars, Niskanen has scored 35 goals and 132 assists with a plus-39 rating.
