Who is the 49ers RB2?
Kaelon Black is the 49ers RB2 behind Christian McCaffrey, which makes him the back in line for the workload if Christian McCaffrey misses time — the handcuff.
Who backs up the 49ers at running back?
A handcuff is the backup who inherits the starter's workload if the starter gets hurt — so the 49ers handcuff is whoever sits directly behind Christian McCaffrey on the depth chart above. Rostering him is how you protect a starting back you have already spent a pick on. More on what a handcuff is.
Christian McCaffrey drew 129 targets, 7.59 a game, and played 88.9% of San Francisco's pass snaps. No other back in the room has a 2025 target, carry or snap on record. McCaffrey has missed 24 of 85 team games in 5 seasons.
If Christian McCaffrey misses time
The stakes here are as high as this question gets, and the evidence behind the answer as thin.
The stakes: McCaffrey played 84.3% of San Francisco's offensive snaps, the highest share of any running back in the league, on 311 carries and 102 receptions for 924 yards. Almost the entire position would come free at once.
The likelihood: 61 of 85 team games across 5 seasons, 24 missed. A total role and a real absence rate is why this page is read in October as often as August.
The evidence: none. Jordan James, Kaelon Black, Isaac Guerendo and Sincere McCormick have no 2025 snap, carry or reception on record, and Patrick Taylor has only an availability line, 29 of 68 team games. The camp reporting below is the only current information on which of them is closer.
Touches with everyone healthy
Very few, and the reporting below gives the reason — it is about catching, not carrying.
A back playing 84.3% of his offence's snaps leaves little for anyone else, and no other back in this room recorded enough 2025 snaps to clear the hundred a back needs before a share is worth ranking.
That is itself the finding. In a committee the second back has weekly value whether or not the first is hurt. Here he has value only if the first is hurt, which makes this a contingency hold rather than a rotation piece — unless one of them can take the passing-down work, which is the argument the reporting below is having.
Is there a passing-down back?
No, and it is the reason the backups have not played.
McCaffrey drew 129 targets, 7.59 a game — a receiver's workload — and caught 102 for 924 yards at 1.62 receiving yards per pass snap. He was on the field for 88.9% of San Francisco's pass snaps against 84.3% of snaps overall, a tilt of +4.6 toward passing downs.
Hold that next to his rushing line, which was -0.54 yards over expected per carry, 46th of 49 qualifying backs. The carries were not creating yards; the receiving role was still enormous. That is the load a replacement would have to absorb, and it is a pass-catcher's load.
The reporting below is explicit that a drop-off in receiving ability is what has kept the younger backs off the field. Whoever solves that gets snaps whether McCaffrey is healthy or not.
What the beat is reporting
What the beat is reporting, last refreshed 2026-09-08. Nothing here is measured — it is reporting, attributed and dated.
Jordan James and Kaelon Black are competing for the RB2 role, with neither reported ahead as of publication (Pro Football Rumors, 2026-07-22).
San Francisco ranked Black as the No. 2 rusher in its draft evaluation, behind only third overall pick Jeremiyah Love (Pro Football Rumors, 2026-07-22).
Isaac Guerendo suffered a pectoral tear and is aiming to be cleared by the end of training camp (Pro Football Rumors, 2026-07-22).
McCaffrey missed practice from Aug. 8 through Aug. 22 with what the team called tightness, which fueled speculation of a hold-in for a new contract, before he returned to full practice on Aug. 23 and said the absence was a planned ramp-down ahead of the season (NBC Sports Bay Area, 2026-08-24).
McCaffrey's 413 touches in 2025 were the most by any player in a regular season since DeMarco Murray had 449 in 2014 (The San Francisco Standard, 2026-06-01).
The last time McCaffrey carried a load that size, 355 touches in 2023, bilateral Achilles tendinitis derailed the following season (The San Francisco Standard, 2026-06-01).
Kyle Shanahan has not been comfortable giving McCaffrey significant breathers because of the steep drop-off behind him in receiving ability (The San Francisco Standard, 2026-06-01).
Kaelon Black can catch, and the team believes he was the best pass-protecting back in the 2026 draft class (The San Francisco Standard, 2026-06-01).
