Everything you need to know for the Boston Celtics' away game against the Miami Heat on January 15, 2026: where to watch, listen, stream info, TV channel, and what happened last game.

Whenever the Celtics and Heat get together, you can't count on some good ol' fashioned rivalry-laden basketball to be played

After a tough loss to the Spurs (27-13) on Saturday night and a frustrating loss to the Pacers (9-32) on Monday night, the Celtics (24-15) will look to right the ship on Thursday night in South Beach as they take on one of their biggest rivals in the Miami Heat (21-19).

Similar to Boston, Miami was thought to be in a position this season where the organization was in a rebuild/retool phase after trading away their best player last season in Jimmy Butler. While other talented parts remain on the roster, Miami was seen as a team in no man's land with a bunch of good-not-great pieces in a league that demands you have at least one superstar to be the straw that stirs the drink.

But as they always do, Miami has found a way to stay afloat as one of the top teams in the Eastern Conference, leaning on the strength of one of the best coaching staffs in the league led by Eric Spoelstra, who is now in his 18th season manning the sidelines for the Heat.

That infrastructure has kept Miami a consistent winner throughout his entire tenure, even as they’ve navigated the gaining-and-losing of stars through the years. Regardless of who is on the roster, Spo is going to get his guys to play hard and be competitive.

For the first time in his young head coaching career, Joe Mazzulla is showing that he has some of that same DNA, as Jayson Tatum remains out while rehabbing his surgically repaired Achilles. While it feels like the 27-year-old is going to make a return to the court sooner than originally anticipated, Boston has vaulted themselves to the top of the conference, sitting as the the No. 3 seed in the conference as of publishing.

Whenever these two get together, no matter the circumstance, we are in for some good ol’ fashioned rivalry-laden basketball.

Enjoy the hoops!

Missed any of Monday night’s loss to Indiana? Here were some takeaways:

1. Shooting Gap Was Real, Yet Nearly Survivable:

The Celtics got the looks they wanted. They just didn’t get the results.

Boston shot 9 for 35 from beyond the arc (25.7%), while Indiana converted 16 of 37 (43.2%).

That difference alone typically determines outcomes, yet the Celtics were in contention late by dominating elsewhere.

Boston owned the paint (54-38) and dominated second-chance points (16-6). They defended persistently and rebounded forcefully. They created offense beyond jump shots.

Achieving all this without Brown made the loss more painful. Boston would have won if even a few extra open threes had fallen.

2. Payton Pritchard Continues Answering The Call:

The Celtics are now 2-1 in games Jaylen Brown has missed this season, and Pritchard has been central to all of them.

He led Boston with 23 points and 8 assists, including 11 in the third quarter as the Celtics dug out after Indiana’s 20-4 run. His offense keeps Boston afloat without their top scorer.

Even in defeat, this was another reminder:

Pritchard isn’t just logging minutes, he’s shaping stretches of games.

3. Wing Rotation Remains Unsettled:

With Brown out and Sam Hauser sidelined, Boston again shuffled its wings.

Baylor Scheierman, typically not in the starting lineup, got his first start of the season at the wing position. He played 20 minutes but contributed just 2 points. That’s a far cry from the performance he gave on Saturday night in a loss to the Spurs.

Jordan Walsh, also playing on the wing, made a bigger impact with 6 points and 9 rebounds and finished the game alongside the starters.

Hugo Gonzalez, another wing, continued to see meaningful minutes.

This isn’t a criticism as much as an observation:

The Celtics are still searching for consistency among their backup wings. That stability is needed more when injuries force rotation changes - and right now, that’s the case.

4. Timing Of This Skid Matters:

Last week, the Celtics surged into the No. 2 spot in the East.

Now, they’ve dropped three of their last four, all tight games decided late against Denver (26-13), San Antonio, and Indiana. None were blowouts. All exposed thin margins when offense stalls and stars are missing.

And it doesn’t get easier.

Boston is in the midst of a four-game road swing, with Miami tonight, followed by Atlanta (20-22) and East-leading Detroit (28-10). This stretch will challenge depth, execution, and Boston’s ability to regain stability without pressing.

Monday’s loss wasn’t alarming.

But it was revealing.

As the Celtics move forward, these are the types of games where health, shooting variance, and role clarity will become critical - and where tightening up could make all the difference before close losses turn into something more concerning.
