What happened: Tobias Harris sustained a left calf strain during training camp. The San Antonio Spurs announced he will be reevaluated after the preseason and is questionable for the October 20 regular-season opener against the Oklahoma City Thunder.

Why it matters: Harris joined San Antonio this offseason on a two-year, $31 million deal to provide veteran scoring. Missing the preseason will delay his on-court integration with his new teammates.

What to watch: The Spurs will issue an update on Harris following the conclusion of their preseason schedule.
