49ers Sign Zamir White as Backfield Injuries Pile Up Behind McCaffrey
White joins a battered San Francisco RB room after McCaffrey missed Monday's practice with tightness — the fourth SF back on the shelf.
Depth flier only until we see how the RB room shakes out.
- White: 198 career carries, 736 yds, 2 TD in 45 games
- Just 12 carries for 32 yds in 6 games in 2025
- McCaffrey missed Monday practice with tightness
- James, Black, Guerendo all sidelined for SF
- White was a 4th-round pick by Vegas in 2022
The 49ers are bringing in veteran running back Zamir White, per ESPN's Adam Schefter, adding another body to a backfield that suddenly looks thin. White, 26, just wrapped his rookie deal with the Raiders after the 2025 season, a fourth-round pick in 2022 who's totaled 198 carries for 736 yards and two scores across 45 games with nine starts.
The timing tells the story. Christian McCaffrey — our RB1 heading into 2026-27 — sat out Monday's practice with tightness, and he's got company on the sideline. Jordan James, Kaelon Black, and Isaac Guerendo have all been sidelined too, which is why San Francisco worked out Nyheim Miller-Hines earlier in the week before landing on White.
Let's be clear about what White is and isn't. His 2025 was a footnote: 12 carries for 32 yards and four catches for 24 yards over six games in Vegas. That's not a workhorse profile emerging — that's a hedge signing for a team that needs healthy legs in camp.
What It Means for McCaffrey
For CMC managers, the tightness is the real headline, not White. McCaffrey put up a monster 2025 — 1,202 rushing yards and 10 rushing TDs, plus 102 catches for 924 yards and seven scores, good for 417 PPR points and our top overall ranking. But his form dipped late, running 3.4 fantasy points below his season average over his final five games, and his injury history makes any August practice absence worth flagging.
The Fantasy Read
White isn't a draft-day target in redraft leagues, full stop. He's a name to file away in deep dynasty and best-ball formats where San Francisco's backfield chaos could hand someone touches. Guerendo and James both sit unranked and scored zero PPR points in limited 2025 action, so the pecking order behind McCaffrey is genuinely open.
Bottom line: keep drafting McCaffrey at the top with eyes wide open on the tightness, and let White marinate on your watch list. If CMC's absence lingers into the preseason, the calculus on this whole room changes fast.
