Despite their dominance, the Celtics have rarely had their full starting lineup intact this season, a concern that lingers with the playoffs fast approaching. Between Jayson Tatum, Jaylen Brown, Kristaps Porzingis, Jrue Holiday, and Derrick White, Boston has struggled to keep its elite starting group on the floor together.

Kristaps Porzingis made a strong return from illness against the Nets on Saturday, leading the Celtics with 24 points, while Tatum contributed 20 points, eight rebounds, and eight assists.

However, the victory came at a cost, as Brown suffered back spasms in the third quarter and did not return. Ahead of Tuesday’s matchup, the Celtics confirmed that Brown would not be available due to a right knee injury. However, he might not be the only starter on the sidelines.

Boston released its injury report on Monday, listing Tatum as questionable with right knee tendinopathy. If the five-time All-Star is unable to suit up, it will mark his third missed game in the last eight contests.

Tatum has been the Celtics’ most reliable player this season, leading the team in scoring with 27.1 points per game, while also averaging 8.7 rebounds, 5.9 assists, and 1.1 steals. His consistent performances have kept Boston near the top of the standings, and he remains a frontrunner in the MVP race.

While his presence is crucial, the Celtics have been surprisingly resilient in his absence, boasting a 4-1 record without him this season. Still, facing a Nets team eager to avenge Saturday’s loss without both Tatum and Brown would present a significant challenge.
