Calvin de Haan could miss the start of next season for the Carolina Hurricanes after having surgery on his right shoulder.
The 28-year-old defenseman will be out 4-6 months. He was injured during a regular-season game against the Pittsburgh Penguins on March 31 and returned for Game 4 of the Eastern Conference First Round against the Washington Capitals, playing 12:21 in a 2-1 win at PNC Arena on April 18. De Haan finished with one goal and a plus-3 rating in 12 Stanley Cup Playoff games.
Signed to a four-year, $18.2 million contract by the Hurricanes on July 3 after six seasons with the New York Islanders, de Haan had NHL career highs in hits (187) and takeaways (59) while finishing with 14 points (one goal, 13 assists) in 74 regular-season games. The No. 12 pick in the 2009 NHL Draft missed the final 49 games of last season with a shoulder injury.
Jordan Martinook will need 4-6 weeks to recover after having surgery Tuesday to repair a core muscle injury. The 26-year-old forward had NHL career highs in goals (15), game-winning goals (five), shots (146) and hits (199) while tying his NHL career-best 25 points, set with the Arizona Coyotes in 2016-17. He made his playoff debut for the Hurricanes, finishing with four assists in 10 games.
