The Boston Celtics erased a 19-point deficit in game one of their first-round playoff series with the Atlanta Hawks, but their comeback ultimately fell short, and the Celtics lost 102-101 Saturday night at Philips Arena.

Over the first two quarters, the Celtics were just 12-of-52 from the field and 2-of-16 from 3-point range. Boston trailed 51-34 at halftime but outscored Atlanta 67-51 in the second-half and even went up by three points in the fourth quarter.

Al Horford had 24 points and 12 rebounds, and Jeff Teague added 23 points and 12 assists for the Hawks. Kent Bazemore scored 23 points.

Isaiah Thomas scored a game-high 27 points and Marcus Smart scored 15 points for the Celtics.

Avery Bradley left the game in the fourth quarter after suffering a hamstring injury. After the game, Celtics coach Brad Stevens said Bradley heard "a pop," but the team wasn't sure how much time Bradley would miss because of the injury.

The Celtics and Hawks will play game 2 of the series Tuesday night in Atlanta.
