Nathan Horton plays; Milan Lucic out

BOSTON -- After missing the last two games with an undisclosed upper-body injury, Boston Bruins winger Nathan Horton was in the lineup Tuesday night against the Ottawa Senators at TD Garden.

However, forward Milan Lucic did not play in Tuesday's 6-0 win due to an undisclosed injury, according to the Bruins.

Lucic, who is listed as day to day, was injured late in Monday's game against the Pittsburgh Penguins. In 41 games this season, Lucic has 16 goals and 12 assists for 28 points, including a plus-11 rating.

Horton left practice early Friday with what the team described as "discomfort" and did not play in the Bruins' 3-2 overtime loss at Montreal on Saturday or in the come-from-behind 4-2 win at Pittsburgh on Monday night.

Horton entered Tuesday with 12 goals and 14 assists in 39 games this season and was a plus-15. He snapped a nine-game scoreless streak with a goal and an assist in a 2-1 win at Toronto on Jan. 3.
