As teams prepare to set their protected rosters in advance of the Seattle expansion draft, trades are starting to come more frequently.

On Friday evening, the New York Islanders moved a veteran off their blue line. The Isles traded Nick Leddy to the Detroit Red Wings for forward Richard Panik and a second-round pick in the 2021 NHL Draft (No. 52 overall — originally owned by Edmonton).

Detroit is retaining 50 percent of Panik’s $2.75 million cap hit.

Leddy and Panik are both former Chicago Blackhawks.

The Islanders acquired Leddy from Chicago in Oct. 2014 in a five-player deal. Chicago sent Leddy and goaltender Kent Simpson to the Islanders for Ville Pokka, Anders Nilsson and T.J. Brennan.

Leddy produced three 40-point seasons from the blue line during his run with the Islanders.
