The Pittsburgh Penguins acquired veteran defenseman Ron Hainsey from the Carolina Hurricanes on the same day they announced that defenseman Trevor Daley will miss six weeks after undergoing knee surgery.
Pittsburgh sent a second-round pick this year and prospect Danny Kristo to Carolina in the trade.
Daley injured his knee during the first period of Pittsburgh's 3-1 win over Carolina on Tuesday and required arthroscopic surgery. Daley, 33, has 19 points and is a plus-9 this season.
