The Boston Celtics are on the verge of getting their franchise cornerstone back on the floor.
After suffering a devastating torn Achilles tendon during the 2025 Eastern Conference Semifinals last May, superstar forward Jayson Tatum has officially been cleared for full 5-on-5 scrimmages. While the Celtics have not circled a definitive date on the calendar, insiders are circling March as the target window for his highly anticipated season debut.
Here is the complete tactical breakdown of Tatum’s rehab progression and how Boston has managed to dominate the Eastern Conference in his absence.

The Rehab Assignment: Clearing the Final Hurdles
Transitioning from individual drills to live-action 5-on-5 work is the most critical milestone in a player’s return from an Achilles tear. You cannot simulate game-speed reps, lateral defensive slides, and the chaos of a full court without live bodies.
According to ESPN’s Shams Charania, Tatum is currently participating in these controlled scrimmages during Boston’s recent road swing. The physical recovery is on schedule, but the final phase of his rehab is strictly about conditioning and mental trust.
Charania noted two distinct elements currently at play for the four-time All-NBA First Team selection:
-
Physical Conditioning: Rebuilding the calf strength in both legs to support explosive movements off the repaired Achilles.
-
The Mental Game: Regaining 100 percent confidence in the leg to plant, cut, and elevate in heavy traffic without hesitation.

The Timeline: “When JT Feels Like JT”
The Boston front office is running a masterclass in patience. There is absolutely no rush to force their star back onto the court prematurely.
The organizational mandate is simple: Tatum is in the driver’s seat. The medical staff, team officials, and Tatum’s personal camp are working in unison, but the final green light will come from the player himself. The prevailing locker room sentiment is that the Celtics’ star will suit up only when “JT feels like JT.”
With the calendar flipping to March, a summit between Tatum and the medical team is expected soon to determine if he is fully cleared to ramp up for the postseason push.
Holding the Line: How Boston Survived the East
Perhaps the most shocking storyline of the 2025-26 NBA season is the fact that the Celtics haven’t just survived without Tatum—they have thrived.
Despite missing a player who averaged 26.8 points, 8.7 rebounds, and 6.0 assists last season, and parting ways with key championship-pedigree pieces like Jrue Holiday and Kristaps Porzingis in the offseason, Boston remains an absolute juggernaut.
-
The Standings: Sitting at an elite 38-19, Boston is just 4.5 games behind the surging Detroit Pistons for the No. 1 overall seed in the East.
-
The Momentum: The team is red-hot, winning nine of their last 10 matchups.
-
The Scheme: Head coach Joe Mazzulla has leaned heavily into a gritty, team-rebounding, and defensive-minded identity, empowering young wings and rotational players to step up and absorb massive minutes.
Boston currently holds a two-game cushion over the third-seed New York Knicks and fourth-seed Cleveland Cavaliers. Adding a rested, highly motivated Jayson Tatum to an already elite roster right before the playoffs fundamentally changes the geometry of the Eastern Conference title race.
