Kyle Shanahan provides update on Nick Bosa's calf injury

San Francisco 49ers head coach Kyle Shanahan updated reporters on defensive end Nick Bosa following a calf injury he sustained just before Thursday’s practice. Shanahan indicated that the team does not expect the issue to be long-term, estimating Bosa could be sidelined for a few weeks. The injury was described as occurring during Bosa's warmup routine. While there is no ruling out of injured reserve, the 49ers are hopeful that Bosa will return for the eighth season of his career without complication. Shanahan noted that the team can manage without Bosa temporarily, but emphasized the need for caution to avoid exacerbating the injury over the course of the 18-week season.
