Dennis Seidenberg, who won a Stanley Cup with the Boston Bruins in 2011, has made the decision to retire from the game of hockey. The 38-year-old has not played since May 15th, 2018 with the German national team at the World Cup in Denmark.

"Physically it just does not work anymore, my shoulder and wrists are pretty much done after 15 years in the NHL," Seidenberg told a media outlet in his home country of Germany.

The former defenseman was drafted in the sixth round, 172nd overall, by the Philadelphia Flyers in the 2001. In 2006, he was sent to the Phoenix Coyotes for Petr Nedved, and the following year the Coyotes sent Seidenberg to the Carolina Hurricanes in exchange for center Kevyn Adams. After signing a one-year deal with Florida in 2009, he was shipped to the Boston Bruins at the trade deadline. In 2011 he became just the second German born player to win the Stanley Cup, following in the footsteps of his favourite player growing up, Uwe Krupp. He had 11 points in the playoffs for Boston that season, and was even cited as a potential winner of the Conn Smythe Trophy (it went to goaltender Tim Thomas). At the conclusion of the 2015–16 season, Seidenberg's seven-year tenure with the Bruins ended, as he was bought out from the remaining two years of his contract. He spent the next two seasons with the New York Islanders, but was used sparingly in 2017-2018. After going most of last season unsigned, he inked a deal with the New York Islanders in February to play for the rest of the season, but was never used.

Seidenberg has represented Germany several times in international play and suited up for Team Europe in the World Cup of Hockey in 2016.
