It was unlikely the Lakers were going to be at full strength in their preseason opener — or in any exhibition game — on Monday.

In the first contest of a back-to-back and three games in four nights, head coach JJ Redick announced pregame that Austin Reaves and Walker Kessler would both be out. Joining them on the sidelines are Collin Sexton and Arthur Kaluma.

Walker Kessler jammed his finger on the backboard while Austin Reaves tweaked his ankle, per JJ Redick.

Collin Sexton and Arthur Kaluma are dealing with lower-body ailments.

None of them are dealing with serious injuries and are day-to-day, per Redick. https://t.co/JehtenA9rN

With two projected starters out, the Lakers’ starting lineup included Luka Dončić, likely starter Quentin Grimes and Matisse Thybulle, Ziaire Williams and Kevon Looney.

During training camp, Redick noted that some players had modified participation in practice. He did not reveal names, but also noted that they weren’t considered serious injuries.

It’s unclear how many, if any, of these players were among those modified participants in practice. We’ll get a better idea of how serious these injuries are as well come Tuesday when the Lakers play again against the Warriors.

Ideally, Kessler’s injury, in particular, is short-term so he can build as much chemistry as possible with Luka and Reaves. In that same vein, Reaves getting back as soon as possible is the best-case scenario.

For the devoted fans who caught Summer League, not getting a chance to see Kaluma will be a bummer. He has a skillset that, in theory, could really complement the team’s stars.

Again, though, players were always going to sit out during this opening stretch of preseason games. We’ll have to wait to see how serious, if at all, the injuries are.
