Win or go home for Miami

For the Miami Heat, the season is going down to the final night.

They need a win.

They need some help.

But they still have a chance.

Tyler Johnson scored 24 points, including the game's final four from the foul line in overtime as Miami kept its postseason hopes alive by rallying past the Cleveland Cavaliers 124-121 on Monday night.

The Heat (40-41) remained No 9 in the Eastern Conference, a game behind No 7 Indiana (41-40) and a tiebreaker behind No 8 Chicago (40-41).

"We think it's meant to be," Heat coach Erik Spoelstra said. "But we have to take care of business."

That, and get some assistance.

For Miami to reach the postseason - a near-impossibility after its 11-30 start - either Indiana or Chicago must lose.

Here's Wednesday's slate: Miami hosts Washington (which is locked into the No 4 spot), Chicago hosts NBA-worst Brooklyn, and Indiana hosts Atlanta.

"It's win or go home," Heat guard Josh Richardson said. "Win, and we still might go home."

Hassan Whiteside scored 23 points and grabbed 18 rebounds for Miami. Richardson scored 19 points, James Johnson had 16 and Goran Dragic added 15.

Deron Williams had a season-high 35 points, nine assists and seven rebounds for the Cavaliers, who fell to 0-7 this season when LeBron James doesn't play.

The Cavs were also without Kyrie Irving and Tristan Thompson, and fell a game behind Boston for No 1 in the East.

James sat with a right calf strain, while Irving has a sore left knee.

"I thought the effort was great," Cavaliers coach Tyronn Lue said. "It was unbelievable."

Kevin Love scored 25 points, Channing Frye had 21 and Kyle Korver had 18 for Cleveland, which wasted a double-digit, fourth-quarter lead and lost in OT for the second straight day.

On Sunday, Cleveland was up 26 going into the fourth in Atlanta. This time, the lead going into the fourth was 11.

Miami survived despite two Cleveland four-point plays in overtime, including one by Williams with 34 seconds left that put the Heat down one. But Miami rallied for its 29th win in 40 games.

"Even if we wouldn't have started 11-30, to go to the last game and have an opportunity to be in the playoffs, you would take that," Tyler Johnson said.

"But I think it makes it that much more special knowing everybody was kicking dirt on us two months ago."

Chris "Birdman" Andersen, who played for both Cleveland and Miami, was in a baseline seat opposite the Heat bench.

Andersen won a title in Miami in 2013 and appeared in 12 games with the Cavs this season before being sidelined by a knee injury.

Meanwhile, the league's Last Two Minute Report of Sunday's Cleveland-Atlanta game showed three calls late in regulation and overtime that negatively impacted the Cavs' chances in what became a 126-125 loss.

"It's too late now. It's over," Lue said.

Heat: Dion Waiters (ankle) missed his 12th consecutive game ... James Johnson had nine assists ... Miami had a 20-6 edge in second-chance points and an 8-0 edge in fast-break points.
