49ers see injury attrition at camp, with 20 players sidelined after Wednesday practice

San Francisco’s training camp has carried a persistent injury undertone, and Wednesday’s practice again highlighted how quickly availability can shift. According to Yahoo Sports’ report, the 49ers began the session with 18 players missing from their 90-man roster on the field, then ended the day with the total number of injured players rising to 20.

The key late departures were defensive end Sam Okuayinonu and guard Nick Zakelj, each exiting early with an injury. Okuayinonu left with an ankle issue, while Zakelj’s was an elbow problem, the report said, underscoring the challenge the team faces in keeping its front-line rotation intact during the early camp stretch.

For a team still working through full-speed reps, losing even a couple of starters or regulars can force cascading adjustments. Defensive ends are often involved early in installation and pass-rush tempo work, while interior guards sit at the center of run fits and protection schemes, both of which are foundational for a team building timing before preseason game weeks.

The report’s framing also matters for what’s next: it describes the injuries as a growing thread through camp, not a one-off development. With the 49ers already managing double-digit absences earlier in the week, the Wednesday exit of Okuayinonu and Zakelj suggests the team could face another round of lineup reshaping at the start of the next practice window.

Camp availability affects more than just depth charts. When players miss practice reps, it changes how quickly coaches can evaluate backup combinations, how often certain matchups can be tested, and how reliable early chemistry looks at positions that depend on hand placement and footwork, especially along the defensive front and inside offensive line.

There are no additional injury specifics in the provided report beyond the two noted body parts and the total count of injured players by the end of Wednesday’s session. As a result, it is not yet clear what the timeline looks like for Okuayinonu or Zakelj, or whether the absences will broaden to other positions before the next padded work.

Still, the broad takeaway is clear for the 49ers’ roster planning: the team is practicing with notable attrition, and the next practices will likely determine whether those absences remain limited to the two exits mentioned or whether more players join the list. For 49ers fans and evaluators, the immediate watch point is not who is “next up” on paper, but who can stay on the field long enough to complete the reps needed for the staff to finalize their early depth plans.
