The defending champs battled the Knicks in a thrilling contest that had the crowd inside Madison Square Garden on edge. With less than three minutes remaining, the matchup was going to an exciting finish when Boston lost the ball, and Jayson Tatum lunged towards it – but his right leg gave up, and he immediately collapsed on the court in agony.
Signalling for a timeout and pulling a towel over his head, Tatum lay motionless as the arena fell silent. Everyone knew immediately that something was very wrong. Tatum was carried off the floor, and the Celtics lost the game 121-113. They were on the verge of elimination, staring face-to-face at the end of the season.
Yet in that moment, that wasn’t the team’s biggest worry. All thoughts were about Boston’s megastar. “I mean, at this point, I'm concerned about Jayson,” said Celtics center Al Horford after the game.
“That's the most important to me. The game stuff, we’ll address it. But I’m just hoping that he's OK.”
Devastating news for Boston
A few hours later, the brutal diagnosis hit the basketball world – Tatum had ruptured his Achilles tendon. The serious injury immediately ended his season but also put the next year in jeopardy. The Celtics lost the series and got eliminated. But the biggest question was: how were they going to perform without their franchise player?
Besides Tatum, the team lost other valuable pieces during the offseason. Al Horford signed with the Golden State Warriors; Boston also decided to trade Kristaps Porzingis to the Hawks and deal Jrue Holiday to Portland.
Free agent Luke Kornet took an opportunity with the San Antonio Spurs. Although Boston added youth and new talent to the roster, expectations were modest. Many analysts predicted the Celtics would struggle just to reach the postseason.
Instead, they’ve exceeded nearly every projection.
Five months into the 2025-26 season, Boston sits second in the Eastern Conference - a position very few saw coming.
Rather than fighting for a playoff spot, the Celtics are on pace to host a first-round series. Leading the charge has been Jaylen Brown, who is putting together an MVP-calibre campaign with averages of 28.9 points, 7.2 rebounds, and five assists per game. Derrick White and Payton Pritchard also elevated their games to help fill the massive void left by Tatum.
What was supposed to be a survival season quietly turned into another year of championship contention. Then, the future suddenly became even brighter. Just 10 months after his surgery to repair the torn tendon, Tatum returned.
And he came back in style.
Post-injury homecoming
When the inside sources released the information on Thursday, fans across the globe held their breath in excitement.
Suddenly, all eyes were on Friday night’s game - Boston welcomed the Dallas Mavericks on their home floor, and what originally was a routine matchup turned into a blockbuster. The six-time All-Star and two-time Olympic gold medalist warmed up. And when the starting lineup announcement roared through TD Garden, fans erupted in joy and excitement. He’s back!
“I think it’s going to be a special day, and I know one thing: My first game back will be at home, it will be in TD Garden,” said Tatum back in September.
“It probably will be emotional, but it’s something I’m looking forward to, just running through that tunnel and being on the court again with all of our fans and sharing that moment with them.” His wish came true.
Tatum had 15 points, 12 rebounds, and 7 assists in 27 minutes - eyeing a triple-double in his post-injury premier. The Celtics beat the Mavericks 120–100 and looked more comfortable than ever. Like they never lost their best player.
Overcoming physical and mental obstacles
A torn Achilles requires surgery and many long months of rehabilitation. The timeline of a return can vary; the shorter end is around 10 months, but some players must sit out much longer.
Kevin Durant didn’t play for 18 months after tearing his Achilles tendon in 2019. The recovery process goes beyond the physical healing – there’s also the mental aspect, including trusting the body and overcoming fears. An injury of this kind can end a career.
“I was shocked, and I was scared. It just felt like everything just kind of flashed before my eyes,” Tatum said.
“Everything that I did in my career, and for that moment, it felt like it came to an end. It was heartbreaking. I just couldn't help but think, ‘Am I ever gonna play again?’ To be honest, at that point, I ain't had no hope. I was always optimistic, I always felt like I could overcome anything, but this was different,” Jayson added.
Tatum’s silver lining was that the injury happened in New York, where he could receive the best medical care right away. The first 24 hours are critical - surgically repairing the tendon in this window can significantly shorten the recovery time.
“There's pretty strong data that if you do Achilles surgery within 24 hours of injury, patients have better outcomes,” said Tatum’s surgeon, Dr Martin O’Malley. Tatum got hurt on Monday night and had surgery on Tuesday morning, before swelling could set in.
This immediate action saved him around a month of recovery. After three months, Tatum went to a Patriots’ game without a walking boot. Drake Maye asked him how he was going. “I’m getting better,” Tatum responded.
In late September, Boston held a media day – by that point, Tatum was already posting videos of himself jogging and shooting. He was sharing his progress and giving the fanbase hope while also being clear about not feeling forced to return as quickly as possible.
“No pressure,” Tatum said. “I’ve stated that. There’s no pressure to return back any sooner than when I’m 100% healthy. No pressure from president of operations Brad Stevens, coach Joe Mazzulla, the team, the organisation. The most important thing is that I’m 100% healthy whenever I do come back.”
Boston did get off to a rocky start as the team was trying to figure out a system without Tatum - the Celtics started the season 0-3 after falling to Philadelphia on opening night, then taking losses against New York and Detroit before finally dominating New Orleans to record their first win of the year. After that, they quickly found their identity. And things have only continued to rise since then.
For six seasons, Tatum had led the team in shot attempts. His absence forced the Celtics to reinvent their offensive approach, distributing those opportunities across the roster. As the months passed and Tatum quietly progressed through rehabilitation, Boston kept improving. And after ten months of forced separation, the two came back together.
Chasing the championship again
On Sunday, Boston faced the Cavaliers in Cleveland. The Celtics outlasted the home team 109–98; Tatum contributed with 20 points, three rebounds, and two assists while also hitting a crucial three-pointer with less than two minutes remaining to cut Cleveland’s comeback effort short.
The reunion proved that Boston would need no further adjustments to compete with Tatum again. It almost feels like he never left.
The Celtics were already contenders before their star returned. Now, their championship ceiling has only risen. Tatum’s goal has always been to play meaningful basketball. And with him being ahead of schedule and 100% healthy, it didn’t make sense to him to wait until next season for the opportunity to win again.
As targeting a deep postseason run, reaching the pinnacle, and lifting the Larry O’Brien trophy remains the ultimate goal for Boston, Tatum has a chance to write one of the greatest comeback stories of all time.
