Kiner, undrafted rookie RB for San Francisco, flashed in preseason with balance and burst but suffered a high ankle sprain in the second game vs the Raiders. He landed on IR after SF waived him with an injury designation to clear a roster spot; SF could keep him around on IR or pursue an injury settlement. His long-term status remains a question mark, contingent on rehab and SF’s depth needs.

Kiner flashed as the lone bright spot on offense for SF, totaling 45 yards on 10 carries with a couple of nifty moves to elude tacklers and a 2-yard reception. In a depth-challenged SF backfield, his all-purpose efficiency signals potential as a steady depth option if the regulars aren’t ready and the offensive line holds up.

Kiner logged snaps in the early sequence behind Abdullah and Taylor, hinting at a potential role if injuries persist and depth is tested.

Corey Kiner is another player looking to capitalize on the running back competition, especially with McCaffrey not playing.

Corey Kiner joins the 49ers with a strong college background and impressive elusiveness metrics, making him a prime candidate to thrive in San Francisco's running back system known for developing undrafted talent.
