Checking the schedule only to realize you’re a day early is a specific kind of sports fan heartbreak. If you're frantically Googling what time is the celtics game on tonight, the short, blunt answer is: there isn't one. The Boston Celtics are actually slated to take on the Miami Heat tomorrow, Thursday, January 15, 2026, with tip-off set for 7:30 p.m. ET.
Honestly, it’s a bit of a breather. The C's have been grinding through a dense January stretch, and tonight, Wednesday, is a rare dark night on their calendar. But don't close the tab just yet. While there’s no live action at the TD Garden or down in South Beach tonight, the stakes for tomorrow's game at the Kaseya Center are massive for the Eastern Conference standings.
What Time is the Celtics Game on Tonight (and Why You’re Seeing Thursday)
Basically, the NBA schedule makers gave Boston a 48-hour gap after their recent battles. When the team does hit the floor on Thursday, the broadcast will be handled by NBC Sports Boston for the locals and FDSN-SUN for those down in Florida. If you’re a cord-cutter or living outside the New England bubble, you’ll be looking at NBA League Pass.
The 7:30 p.m. ET start time is pretty standard for East Coast matchups, but as any seasoned fan knows, "7:30" usually means the ball actually goes up around 7:40 p.m. after the anthems and starting lineups are announced.

The Jayson Tatum Situation
You can't talk about the Celtics right now without mentioning the giant, Jayson Tatum-sized hole in the roster. He’s been out since tearing his right Achilles during the 2025 playoffs. While he had surgery back in May 2025, the recovery timeline is a brutal 9 to 12 months.
We’re currently in mid-January. That means we are realistically looking at a late March or early April return at the absolute earliest. Most insiders think Boston might just mothball him until the 2026-27 season if the risk is too high. It’s a bummer, but Jaylen Brown has been playing like a man possessed to keep the ship afloat.
Who is Playing? Expected Lineups for Celtics vs. Heat
Since there's no game tonight, the injury report for tomorrow is still technically "preliminary," but we have a very good idea of who’s suited up. Jaylen Brown is currently listed as day-to-day with some back tightness, but knowing his track record, he’s likely to go.
Boston Celtics Projected Starters:
- Payton Pritchard (PG) - He’s been a revelation this season, averaging over 17 points.
- Derrick White (SG) - The glue guy who somehow blocks shots like a center.
- Jaylen Brown (SF) - Carrying the scoring load at nearly 30 PPG.
- Sam Hauser (PF) - Spacing the floor and proving he’s more than just a shooter.
- Neemias Queta (C) - Providing that much-needed interior presence with Al Horford playing limited minutes.
Miami Heat Projected Starters:
The Heat are their usual "zombie" selves—annoying, disciplined, and dangerous. They’re currently hovering around the 8th seed with a 21-19 record, but they always play Boston tough.
- Norman Powell (Averaging a career-high 23.9 points)
- Bam Adebayo (The defensive anchor)
- Andrew Wiggins (A newer addition to the Heat culture)
- Kel’el Ware (The rookie/sophomore standout who’s been grabbing 10 boards a game)
- Jaime Jaquez Jr. (The Swiss Army knife)
Making Sense of the Matchup
The Celtics are sitting at 24-15, which is good for third in the East. Honestly, considering they’re doing this without their best player, it’s kind of a miracle. Joe Mazzulla has them shooting 15.7 threes per game, which is second in the league. They basically live and die by the arc.
Miami, on the other hand, is a bit of a statistical anomaly. They score almost 120 points per game but also give up a ton. They’ve been involved in a lot of close games lately, going 4-2 in contests decided by 4 points or less. If tomorrow’s game is close in the fourth quarter, the Heat have the "clutch" experience, but the Celtics have Derrick White, who is statistically one of the best fourth-quarter defenders in the league right now.
One weird stat to keep an eye on: the Celtics have been dominant against Eastern Conference opponents, going 17-9 so far. They’ve also held teams to just 45% shooting, which is elite.

Betting Odds and Predictions
While there is no set line yet (books usually wait until the morning of the game), early projections suggest Boston might be a slight favorite, perhaps -2 or -3, even on the road. The "Over/Under" will likely be high, probably around 228.5, given Miami’s recent scoring surge.
Key Tactics to Watch on Thursday
When the game actually starts at 7:30 p.m. tomorrow, keep an eye on the Neemias Queta vs. Bam Adebayo matchup. Queta has been a fan favorite in Boston, but Bam is a different level of athlete. If Queta gets into foul trouble early, the Celtics’ thin frontcourt is going to be exposed.
Also, look at Sam Hauser’s gravity. Even when he isn't hitting shots, he opens up the lane for Jaylen Brown to drive. Miami likes to play a lot of zone defense—Erik Spoelstra is the king of it—and Hauser is the "zone buster" for Boston.
Your Game Day Checklist
Since you don't have a game to watch tonight, use this time to get ready for tomorrow's tip-off.
- Check the Injury Report: Around 1:30 p.m. tomorrow, the NBA will release the official status for Jaylen Brown.
- Download the Apps: If you’re streaming on Peacock, make sure your subscription is active; they’ve been moving more "exclusive" games there lately.
- Sync Your Calendar: The Celtics play again on Saturday, January 17, against Atlanta, so this is the start of a busy weekend.
The Celtics might be missing Tatum, but the "Buffalo" Derrick White and Jaylen Brown have turned this into one of the most resilient teams in the league. Tomorrow night in Miami is just another test of that grit.
Actionable Next Steps:
Set a reminder for 7:15 p.m. ET tomorrow to check the final starting lineups. If Jaylen Brown is ruled out, expect the point spread to swing heavily toward Miami, and Payton Pritchard's "over" on points might become a very popular play. Don't forget to check your local listings for NBC Sports Boston, as some regional providers have shifted channel numbers recently.
