The 49ers didn't onboard too many undrafted free agents, but those who signed have a legitimate shot at a roster spot in 2025.
The San Francisco 49ers came away with 11 total prospects from the 2025 NFL Draft, banking on each of them to play a significant role on a roster that's undergone plenty of change and overhaul since last season.
But the Niners still have to get their offseason roster up to 90 players, and there was plenty of draftable talent that slipped through all seven rounds and into the ranks of the undrafted.
The road for any UDFA player to a roster spot is a long a tough one. Chances are much more limited, and the patience a team gives to such an undrafted player is significantly less than what's given to a first- or second-round draftee.
That said, head coach Kyle Shanahan has a reputation for not caring where (or if) a player was drafted. He opts to put the best player on the field as much as possible, meaning San Francisco's latest crop of undrafted players will have a chance to hang around if it takes full advantage of the limited opportunity.
Immediately after the 2025 draft concluded, the 49ers reportedly came to terms with these five undrafted players.
49ers onboard 5 undrafted free agents (and could always add more)
DL Sebastian Valdez, Washington (Ryan Fowler, The Draft Network)
The Niners' defensive line was a primary focal point of the draft with three of the 11 picks used to address it. But, offseason departures left the depth chart awfully bare, meaning grabbing Washington lineman Sebastian Valdez should help round out the third-team unit without much issue.
He had 48 tackles and two sacks in 2024.
DB Jakob Robinson, BYU (BYU Football)
San Francisco grabbed a couple of small-sized defensive backs, Upton Stout and Marques Sigle, who are versatile and can play both nickel corner and safety, and BYU's Jakob Robinson is the third rookie of this mold added.
At 5-foot-10 and 165 pounds, size is a concern. But he was quite the ballhawk, recording 11 interceptions and 21 passes broken up during his collegiate career.
WR Isaiah Neyor, Nebraska (Tony Pauline, Sportskeeda)
The 49ers' two drafted receivers were small in stature, Jordan Watkins and Junior Bergen, but that's not the case with Nebraska's Isaiah Neyor at 6-foot-3 and 210 pounds.
Nebraska's offense didn't allow Neyor to flourish much, but he's a promising red-zone threat.
OL Drew Moss, Colorado (Jeremy Fowler, ESPN)
Prioritizing the offensive line didn't seem to be a big deal for the Niners this season, but they at least add some depth with one of head coach Deion Sanders' proteges, offensive lineman Drew Moss, whose 6-foot-4, 300-pound frame signals a lot of work toward the interior.
RB Corey Kiner, Cincinnati (Keegan Nickoson, Bearcat Journal)
Landing Oregon running back Jordan James is a boost, especially considering San Francisco churned through tailbacks last season and then lost Elijah Mitchell and Jordan Mason to offseason transactions.
At least San Francisco can look to Cincinnati's Corey Kiner as a preseason workhorse after he rushed for back-to-back 1,000-yard campaigns for the Bearcats in 2023 and 2024.
