NBA playoff schedule 2013: Heat, Spurs, Knicks could all advance Sunday

The New York Knicks have a 3-0 lead on their longtime rival, the Boston Celtics, and could complete Boston's earliest playoff exit in their current run of six-straight playoff appearances. The teams play at 1 p.m. on ABC.

The defending champion Miami Heat could finish off the Milwaukee Bucks with a sweep at 3:30 p.m. on ABC. Despite Brandon Jennings' prediction that the Bucks would win in six games, the series has not gone well for Milwaukee.

Miami has won each game by double-figures, but the Heat do have at least one question heading into Sunday's game: how healthy is Dwyane Wade? Wade, who has an injured right knee, has reportedly been getting treatment on it. The Heat have not decided whether or not Wade will play Sunday.

The San Antonio Spurs could finish off the ailing Los Angeles Lakers with a win at 7 p.m. on TNT. The Lakers, already playing without guards Kobe Bryant, Steve Nash, Steve Blake and Jodie Meeks, will also reportedly be without Metta World Peace on Sunday. Andrew Goudelock, Darius Morris and Earl Clark will all start for the Lakers.

In Sunday's final game, the Golden State Warriors will try to continue their improbable upset bid over the Denver Nuggets, despite playing without injured All-Star David Lee. The Warriors, leading the series 2-1, host the Nuggets at 9:30 p.m. on TNT.
