The San Francisco 49ers are facing a precarious situation as their running back depth chart takes a significant hit. With positive health reports surrounding star running back Christian McCaffrey this summer, the team’s fortunes hinge heavily on keeping him in top form. However, the recent injury to backup running back Isaac Guerendo has exposed vulnerabilities in the 49ers’ roster, raising concerns about their ability to withstand another injury to their star player.
Head coach Kyle Shanahan announced on Monday that Guerendo, a promising second-year running back, is expected to miss “a couple of weeks” due to a shoulder injury. This setback comes at a critical time, as the 49ers already traded away talented backup Jordan Mason to the Minnesota Vikings earlier this offseason. The Mason trade was partially tied to the acquisition of Guerendo, a move that now leaves San Francisco with limited options behind McCaffrey.
McCaffrey’s health is paramount for the 49ers, especially after a 2024 season where he missed nearly all games due to two separate injuries. His absence was a major factor in the team’s disappointing 6-11 record, underscoring his importance to the offense. Without a reliable backup, the 49ers’ margin for error is razor-thin. Guerendo was expected to fill that critical role, but his current injury casts doubt on his availability for the start of the regular season.
Behind McCaffrey, the 49ers are now relying on two relatively untested players: fifth-round rookie Jordan James and Patrick Taylor Jr. While both have potential, their lack of NFL experience is a concern for a team with Super Bowl aspirations. To bolster their depth, the 49ers recently signed veteran running back Ameer Abdullah, a move that could prove to be a stroke of foresight—or simply a fortunate coincidence. Abdullah brings a wealth of NFL experience, which could stabilize the position if Guerendo’s recovery lingers.
The 49ers’ next moves will reveal their confidence—or lack thereof—in their running back depth. If they pursue another veteran running back in free agency, it could signal that Guerendo’s injury is more serious than initially reported, potentially impacting the early weeks of the season. Additionally, the team must navigate the preseason with enough healthy running backs to avoid further strain on their roster.
Conversely, if the 49ers hold steady without additional signings, it may indicate optimism about Guerendo’s recovery timeline. While McCaffrey’s health remains the top priority, having a capable backup is essential for a team that learned the hard way last season how quickly injuries can derail a campaign. Guerendo was poised to be that insurance policy, but his injury has thrust the spotlight back onto McCaffrey’s durability.
As the 49ers prepare for the upcoming season, all eyes will be on McCaffrey. His ability to stay healthy could be the difference between a return to glory and another nightmare scenario for San Francisco. For now, the team can only hope that Guerendo’s absence is brief and that their star running back remains the cornerstone of their Super Bowl dreams.
