State Farm NBA Play-In Tournament status as of May 10.

Down 26 points at halftime, the Celtics fought back but ultimately lost a pivotal showdown with the Heat, who now own a two-game lead over Boston for the No. 6 seed in the Eastern Conference.

While the Celtics’ hopes for an outright playoff berth are certainly dimming, they do get to play the Heat again Tuesday night (7:30 ET, TNT) with the head-to-head tiebreaker at stake. A win would keep Boston alive for the No. 6 seed, but a loss all but guarantees an appearance in the State Farm Play-In Tournament.

Meanwhile, in the Western Conference, the Kings and Pelicans kept their slim playoff hopes alive and Anthony Davis had his best game of the season to keep the Lakers in the hunt for the No. 6 seed.

The Pacers appear destined for the 8-9 Play-In game — as long as they don’t go into a freefall. Here’s how it shapes up: After Monday’s game at Cleveland (7:30 ET, NBA League Pass), Indiana ends with home games against teams they have not been able to solve this season in Philadelphia (0-2), Milwaukee (0-2) and the L.A. Lakers (0-1). Their finale is vs. Toronto in Tampa (1-1).

The Mavs overcame Luka Doncic’s ejection early in the second half to beat the Cavs on Sunday night and extended their lead to one game over the Blazers in the battle for fifth place in the West. Dallas needs any combination of wins or Lakers losses adding up to 3 to avoid the Play-In Tournament.

Record: 32-35
Games Ahead (11th): 1.5
Games Back (6th): 6.5

Last Result: 124-102 L @ POR
Next Opponent: vs. MIL on Monday

The Spurs will most likely limp into the Play-In — if they get in at all. Losers in six of its last seven, San Antonio’s lead over New Orleans for the No. 10 seed is just 1 1/2 games. The Spurs host the Bucks to open the final week of their regular season.
