The Penguins finally have all of their players under contract.
Defenseman Marcus Pettersson, who had been a restricted free agent, has accepted a one-year contract with an average annual value of $874,125.
Both sides had been hoping to work out a longer-term deal, but the Penguins' lack of salary-cap space appeared to mitigate against that.
Pettersson, who was acquired from the Ducks for winger Daniel Sprong last December, was coming off an entry-level deal that had an average annual value of $894,125.
Pettersson, 23, had two goals and 23 assists in 84 games last season, including two goals and 17 assists in 57 games with the Penguins.
