Rick Carlisle described the injury as a 'mild tweak of his right ankle.'

Preseason basketball is basically a cardio session with referees, so any injury news immediately sets off alarm bells for a franchise player.

Pacers head coach Rick Carlisle announced that is sitting out tonight's exhibition against the Atlanta . The culprit is a "mild tweak of his right ankle," according to a report from NBA insider Marc Stein.

A "mild tweak" in October is standard coach-speak for a team refusing to risk their cornerstone in a game that matters as much as a Tuesday morning shootaround. There is zero incentive for Indiana to push their star point guard onto the floor for a meaningless tune-up.

Haliburton is the absolute engine of the Indiana offense. Without him pushing the pace, the Pacers go from a relentless track meet to a brisk, highly manageable walk.

For anyone degenerate enough to be looking at preseason spreads or early regular-season MVP futures, this is a quick reminder of how fragile the NBA ecosystem is. You do not panic over a preseason ankle tweak, but you definitely bookmark it if you are holding a ticket that requires him to hit the 65-game threshold for awards.

Indiana has a few more tune-ups before the real games start. Expect Haliburton to spend the next few days in bubble wrap while the rest of the roster fights for rotation minutes against Atlanta.
