Ducks general manager Bob Murray scratched one item off his summer to-do list Thursday, when he signed veteran defenseman Ben Lovejoy to a three-season contract extension. The deal is worth $3.3 million, according to an NHL source. Lovejoy was one of 13 unrestricted free agents in the Ducks organization, a list that also includes Teemu Selanne, Saku Koivu and Toni Lydman. The Ducks also have two restricted free agents in Matt Beleskey, who has arbitration rights, and Kyle Palmieri, who does not. The 29-year-old Lovejoy proved to be a useful player on the blue line for the Ducks after a trade Feb. 6 from the Pittsburgh Penguins. He had 10 assists and a plus-minus defensive rating of plus-six in 32 games for the Ducks, who acquired him for a fifth-round draft pick in 2014.
