Watch Boston Celtics Vs. Indiana Pacers Live Stream: Celtics Go For Sweep, Start Time, Preview, Game 4 Online

After smothering the Indiana Pacers offense for three straight games, the Boston Celtics are looking to eliminate the Pacers completely, finishing off a four-game sweep of the fifth-seeded NBA Eastern Conference team in their first-round playoff series. If Boston can get the job done on Sunday, they will record their first playoff series sweep in 14 postseason series, per NBA.com, having last swept an opponent in their 2011 first-round match against the New York Knicks. But for Indiana, a loss in their upcoming game would mark the second time they have been on the receiving end of a first-round sweep in the last three seasons.

To find out how to watch a live stream of the upcoming Boston Celtics vs. Indiana Pacers game of the first-round NBA Playoff series, see the streaming information at the bottom of this article. The matchup gets underway at 1 p.m. Eastern Time at the 18,000-seat Bankers Life Fieldhouse in Downtown Indianapolis, Indiana, on Sunday, April 21.

That start time is 10 a.m. Pacific Time, noon Central. In the United Kingdom, tipoff time will be 6 p.m. British Summer Time on Sunday.

In Game Three, the Celtics exploded with 41 points in the first quarter, per Basketball Reference, but quickly squandered a 13-point lead to fall behind by two points at the halfway mark. A 21-12 third quarter, however, effectively sealed the road victory for the Celtics — only Jaylen Brown was able to top 20 points for the Celtics, finishing with 23. For offense-starved Indiana, Bojan Bogdanovic led the way with just 15 points.

Though Boston's 49-win regular season was a letdown -- marking their first season-on-season decline in winning percentage in five years, per NBA.com -- the 17-time NBA champs have managed to flip the proverbial switch, at least in the first round of the playoffs.

"I think that you know if you don't bring it, and you know you're going to get punished," said Celtics Coach Brad Stevens, quoted by NBA.com. "There's a fear factor there or a respect factor there."
