Christian McCaffrey, the star running back for the San Francisco 49ers, is expected to participate in Thursday's practice after being inactive for the season opener due to Achilles and calf issues. His participation level remains uncertain, as the team has not ruled him out for the upcoming game against the Vikings. The decision to keep him inactive in Week 1 was made collaboratively with the coaching staff, prioritizing his long-term health over immediate play.

• McCaffrey's practice participation is a positive sign for his availability.
• The decision to sit him out in Week 1 was made for long-term health considerations.
