Current injury status

Reported Sep 7

Day-To-Day

Hartenstein (ankle) participated in an offseason workout with the Thunder on Monday, Clemente Almanza of USA Today reports.

Hartenstein sat out FIBA qualifiers with Germany to nurse an ankle injury he sustained earlier this summer, so it's encouraging to see him back on the court ahead of training camp in the fall. The 28-year-old big man appears to be firmly on track for the start of the regular season in October, barring any setbacks along the way.

How it's counted

Each situation shows this player's numbers in those games, with the difference from their full-season line in parentheses. The definition sits under each situation name. Situations overlap: one game can count in several.

True shooting is one shooting number that folds in threes and free throws; its differences are in points of TS%. Every final box score counts — there is no minutes cutoff. Fewer than 5 games reads as a small sample. These splits describe what happened. They do not prove the schedule caused it.
