Corey Kiner stood out in SF’s preseason, flashing balance and wiggle behind the line. A high ankle sprain in the second preseason game vs. Las Vegas will sideline him for about a month. San Francisco waived him with an injury designation to clear a roster spot for Michael Dunn and Malik Knowles, then he cleared waivers and landed on IR. SF’s options now center on rehab and a possible long-term path or an injury settlement that would push him into free agency.

SF has a history of extracting value from UDFA backs, and Kiner’s burst suggested he could factor in behind Christian McCaffrey. If he can return healthy, he might stay in the mix as a depth option and development project into 2025. An injury settlement would likely end that path, though rehab at SF’s facility keeps doors open and preserves the workout clock.

Knowles and Dunn’s addition shows SF’s patience with youth when injuries hit. Knowles adds WR depth; Dunn strengthens the line. For fantasy, Kiner remains a dynasty hold but a wait-and-see in redraft until SF clarifies his status.

The San Francisco 49ers enter training camp with significant concerns at the wide receiver position, as their struggles from the previous season continue to loom large. Brandon Aiyuk's participation is uncertain due to a lingering injury, while Deebo Samuel's performance remains inconsistent. The team is heavily relying on Jauan Jennings to step up as a top target, particularly in Aiyuk's absence.

Ricky Pearsall, fresh off recovery from a gunshot wound, needs to prove his durability, while the addition of veteran Demarcus Robinson aims to bolster their receiving corps. With rookies like Jacob Cowing and Jordan Watkins looking to earn snaps, the 49ers must use the preseason to establish a reliable receiving unit. Meanwhile, Russell Gage's comeback adds another layer of intrigue as the team navigates through injuries and expectations.
