The Dallas Stars acquired center Derek Roy from the Buffalo Sabres on Monday in a trade that sent forward Steve Ott and defenseman Adam Pardy to Buffalo.
Roy, 29, had 17 goals and 27 assists in 80 games for Buffalo in 2011-12.
"Derek Roy is a legitimate top two line center, and has been productive throughout his career," Stars general manager Joe Nieuwendyk said in a statement. "He is a proven commodity that helps fill a void at a position of need for our club. We believe Derek helps make our hockey club better and we are happy to have him."
Ott, 29, scored 11 goals and added 28 assists in 74 games for Dallas this past season. He also had 156 penalty minutes.
Pardy, 28, had three assists in 36 games with the Stars in 2011-12.
