Miami, which has won four in a row and 14 of its last 15, is playing four road games in five days. The Knicks, meanwhile, have won two straight after the public feud between coach Larry Brown and point guard Stephon Marbury.
Miami has beaten New York six straight times.
The Heat overcame poor shooting and a subpar game from Dwyane Wade to beat Chicago 85-84 on Saturday afternoon.
Wade went 1-for-8 from the field and had 10 turnovers, but was 13-for-13 from the free-throw line to finish with 15 points.
Wade had been shooting 59 percent and averaging 34.4 points in his previous five games, but struggled in his return to his hometown.
“Just get it back to Miami,” Wade said. “Out in Chicago I never play good. I have a long career ahead of me, so one day I will get one good game in.”
“It was a weird game. There was ugly shooting and a lot of turnovers and mistakes and we were just fortunate to get the win,” O’Neal said. “I should have done better but it was just a very ugly and weird game.”
Miami gets a day of rest on Monday, then plays Minnesota and Detroit the next two days.
Brown and Marbury have claimed their verbal sparring is over. Marbury said he wanted more freedom offensively while Brown said he had already given him more freedom than any point guard he’s ever coached.
New York beat Detroit 105-103 on Friday night on Jamal Crawford’s jumper with 2.2 seconds remaining. That followed a double-overtime victory over Atlanta on Wednesday.
Marbury and the starters didn’t play after the third quarter against the Hawks, and sat on the bench for all or most of the fourth quarter against the Pistons.
“I saw them playing hard,” Brown said. “That’s all we can do from now on. We’ve got to find out who in that locker room is committed to do that every night. There were a lot of really positive things, and hopefully we can build on that.”
After enduring a stretch where they lost 22 of 24 games, the Knicks have won four of their last six games, and shot a season-high 56.9 percent against Detroit, displaying energy that has been lacking throughout the season.
“It’s been there. At times we’ve had it and at times we haven’t,” Crawford said. “But now we’re learning how to finish close games. I think that’s going to make us better in the long run.”
