Aulie appeared in 17 games for the Maple Leafs this season and had two assists. In 57 games over two NHL seasons, the 22-year-old has two goals and four career points.

Lightning general manager Steve Yzerman announced the deal before Monday’s NHL trade deadline. In other moves, Tampa Bay acquired defenseman Mike Commodore from Detroit in exchange for a conditional seventh-round pick in 2013 and obtained defenseman Brian Lee from Ottawa in a trade that sent defenseman Matt Gilroy to the Senators.

Lee scored one goal and had seven assists in 35 games with the Senators this season. He made his NHL debut with Ottawa during the 2007-08 season and has five goals and 28 points in 167 career games.

The ninth overall pick in the 2005 draft was sixth among rookie defensemen with 13 points during the 2008-09 season.
