SANTA CLARA, Calif. - After missing the San Francisco 49ers' season opener due to calf and Achilles issues, running back Christian McCaffrey spoke out about the decision to keep him inactive and expressed his unwavering confidence in his ability to play.

During a media session before Wednesday's practice, McCaffrey explained that his mindset every week is geared towards playing, regardless of any physical setbacks. He acknowledged that there have been weeks where he felt unable to even participate in practice, only to wake up on game day feeling capable of performing. Despite his disappointment at being benched, McCaffrey sees the decision as a strategic move that could benefit him throughout the rest of the season.

Coach Kyle Shanahan revealed that McCaffrey's Achilles tendinitis has been the primary concern, as its severity fluctuates. However, Shanahan dismissed any speculation about placing McCaffrey on injured reserve, emphasizing the team's confidence in his eventual return.

With a shorter recovery period between games due to Monday night's matchup, the 49ers faced a tight schedule to prepare for their upcoming game against the Minnesota Vikings. McCaffrey is expected to have limited participation in Wednesday's practice, part of a cautious approach to manage his injury.

McCaffrey's calf injury first surfaced during August, but it was only last week that the Achilles issue was disclosed in the official injury report. Throughout the week leading up to the season opener, he participated in limited practice sessions and expressed no doubts about playing against the New York Jets, hoping to take on his usual workload.

The running back clarified that his current calf and Achilles injuries are unrelated to last season's calf issue. He remains determined to overcome these challenges and return to full fitness.

Looking ahead to this week's game, McCaffrey's status remains uncertain until closer to kickoff. Questions have arisen about the impact of playing on artificial turf, but the running back dismisses any concerns, firmly believing that if he is physically able to play, he will be on the field.

In a similar scenario last season, McCaffrey played against the Vikings on the road despite being listed as questionable and practicing on a limited basis due to an oblique injury. He put up impressive numbers, accumulating 96 scrimmage yards and two touchdowns, although the 49ers ultimately suffered a 22-17 loss.

In the absence of McCaffrey, Jordan Mason had an impressive outing against the Jets as he made his second start in the NFL, rushing for 147 yards and a touchdown. McCaffrey commended Mason for his performance on short notice.

Despite the uncertainty surrounding his availability, McCaffrey remains resolute in his belief that he will be on the field this week. Maintaining a positive mindset, he asserts his readiness to contribute to the team's success.

As Sunday's kickoff approaches, fans and the team eagerly await the final decision on McCaffrey's playing status. His determination to overcome his injury and contribute to the team's efforts is a testament to his unwavering commitment.
