Florida traded Leopold to Pittsburgh for a second-round pick in the 2010 NHL Entry Draft. The move was announced Monday, two days before the league's trade deadline.
The 29-year-old Leopold signed a one-year contract with the Panthers in July. In the summer, he was part of a deal that sent the rights to defenseman Jay Bouwmeester to Calgary.
Leopold has seven goals and 11 assists in 61 games for Florida this season. The Minnesota native has played in 416 games in his NHL career.
