New York will be without rookie Iman Shumpert, its best perimeter defender, who blew out his knee on Saturday. However, Tyson Chandler should be feeling better after being questionable to play due to a flu.
Either way, the Knicks will have to find another gear to challenge the Heat, who appear to have been rejuvenated by the start of the playoffs. LeBron James, the front-runner for the 2012 MVP award, was dominant, with 32 points, four rebounds, three assists and four steals on 71 percent shooting.
Carmelo Anthony, meanwhile, struggled mightily with Miami's defensive strategy, as the Heat fronted him in the post to deny him easy post-up position. He scored 11 points while going 3-15 shooting on Saturday.
The 6 p.m. game will be televised nationally on TNT.
