The TD Garden was swarming with police Friday night for the playoff game between the Boston Celtics against the New York Knicks.

Both outside the building and on the floor.

The Celtics honored the first-responders from last week's Boston Marathon attack during the game, their first at home since the April 15 bombing at the race's finish line.

"They've been through a lot,'' said Celtics coach Doc Rivers, whose father was a police officer in the Chicago area. "I think they can't get enough support; they can't get enough love. So I think it will be wonderful for them and for the fans as well.''

The Celtics were scheduled to play Indiana in Boston in their regular-season finale April 16, the day after the bombings. The game was canceled, and the Celtics began the playoffs in New York, where they went down 0-2 in the best-of-seven series.

Now they're back at the Garden, hoping to turn the series around.

An honor guard from the Boston police, fire and emergency medical services brought out the American flag, and a cappella group Voices of Freedom, in military uniforms, sang the "Star-Spangled Banner'' before the game.

Doctors and nurses who treated the injured were to be recognized as "Heroes Among us,'' along with volunteers from the Boston Athletic Association.
