OTTAWA (AP) _ The Ottawa Senators, looking to bolster their defense, acquired defenseman Craig Millar from the Tampa Bay Lightning on Tuesday for forward John Emmons.

The Senators, with the best record in the Eastern Conference, made the deal on the day of the NHL trade deadline.

Millar had one goal, one assist and 16 penalty minutes in 21 games with the Lightning.

Emmons, playing on Ottawa's fourth line this season, had one goal, one assist and 20 penalty minutes in 41 games.

He became expendable after the Senators obtained forward Eric Lacroix from the New York Rangers last week.
