For those looking for NBA streams, our comprehensive guide at /nba-streams provides all the information you need to watch the game live.

A Look at the Celtics

The Boston Celtics, coming off a strong but ultimately frustrating playoff run, enter the season with high expectations. However, their hopes are significantly tempered by a concerning injury report. Superstar Jayson Tatum will be sidelined until April 2026 due to Achilles surgery, a massive blow to their offensive firepower. Jaylen Brown is listed as day-to-day following knee surgery, leaving his availability for the opener uncertain. Anfernee Simons and RJ Luis Jr. are also dealing with day-to-day injuries, adding another layer of uncertainty to the Celtics' starting lineup. The Celtics will heavily rely on the leadership and performance of Marcus Smart and the rest of their supporting cast to compensate for the absence of their key players. Their recent form shows a mixed bag, with a 2-3 record in their last five games against the New York Knicks. The wins showcased their ability to dominate, but the losses highlight their vulnerability without a fully healthy roster.

The Cavaliers' Challenge

The Cleveland Cavaliers also face injury concerns heading into their season opener. Star point guard Darius Garland is out until November 1st due to toe surgery. Lonzo Ball, Craig Porter Jr., and Sam Merrill are all listed as day-to-day, meaning their participation in the game hangs in the balance. This absence of key players, especially Garland, could significantly impact their offensive rhythm and overall team performance. Their last five games against the Indiana Pacers show a similar pattern to the Celtics – a struggling team trying to find consistency. They’ve also recorded a 1-4 record in their last five games, raising questions about their readiness for the season opener.

Key Matchup: The Battle in the Backcourt (and Beyond)

Even with the injuries, this game promises a compelling backcourt battle, though potentially with altered lineups. The Celtics' Terry Rozier and the Cavaliers' Donovan Mitchell are both capable of explosive performances and will need to step up in the absence of their injured teammates. The Celtics will rely on their defensive intensity to contain Mitchell, while the Cavaliers will look to exploit any weaknesses in the Celtics’ rotations.

Beyond the backcourt, the battle in the frontcourt will also be critical. While both teams are dealing with injuries to their big men, the Celtics and Cavaliers both have players who can make a significant impact at center and power forward. This match-up is likely to be a physical battle, with plenty of rebounding and post play expected. The overall depth and ability of each team's bench will be tested in this crucial season opener.

The TD Garden Advantage

The game will be played at the iconic TD Garden, known for its passionate and vocal fanbase. The Celtics often benefit from a significant home-court advantage, and this could play a role in the outcome, especially considering the Cavaliers' travel and the injuries affecting both teams. The atmosphere at the TD Garden is expected to be electric, adding an extra layer of excitement to an already compelling matchup.
