Impact The injury that forced McCaffrey to miss the entire preseason slate was termed a strained calf, but Shanahan tacked on Achilles in his session with the media Thursday. There doesn't seem to be much worry about McCaffrey's availability for Monday's Week 1 matchup with the Jets, but his status nonetheless bears watching in the coming days. Behind McCaffrey, Jordan Mason is the likely next man up at running back for the 49ers with Elijah Mitchell (hamstring, IR) out for the season, and Isaac Guerendo (groin) and Patrick Taylor also are on the team's active roster.
