Ellerby, 24, has been with the Panthers for four seasons. He appeared in nine games with the Panthers this season, but did not register a point, has a minus-2 ranking and 36 penalty minutes. For his career, he has made 125 NHL appearances, scoring two goals and 17 points while having a minus-21 rating.
A first-round pick (No. 10) in the 2007 NHL Draft, Ellerby was averaging a little more than 15 minutes per game. His place in the defensive rotation, however, became tenuous with the return of Erik Gudbranson to the mix. Gudbranson, 21, played more than 20 minutes in the victory against the Philadelphia Flyers on Thursday night.
