Active injury intel pulled from: Official team reports | Updated: 12:30 PM ET

Chicago Bears

• QB Caleb Williams: No major concerns — monitor practice.
• RB rotation: Clean, Khalil Herbert set for full reps.
• WR DJ Moore: Cleared to play. No setbacks.

Impact profile: Full-squad offensive script vs 49ers secondary.

San Francisco 49ers

• RB Christian McCaffrey: Active and a workhorse all year.
• WR Brandon Aiyuk: Practice closely watched, trending positive.
• LT Trent Williams: Managed reps as usual, expected to anchor the line.

Impact profile: Elite offense at home, minimal injury drag at skill positions.

1) Caleb Williams vs. 49ers Pressure

• San Francisco’s blitz rates spike on 3rd down. Rookie QBs have posted below-median EPA against them.
• Williams must read Warner/Greenlaw and get the ball out under 2.5s to avoid negative plays.

2) 49ers’ Run Game vs. Bears Front

• McCaffrey faces a Bears defense giving up 4.4 ypc since Week 14. Expect Shanahan to scheme heavy zone/outside looks.
• Bears’ young LBs have graded out well but can be exposed by deceptive shifts/motion.

3) First-half Volatility

• Early primetime nerves for Williams could lead to one big play or critical mistake — consider 1H UNDER triggers if wind/weather moves in.
• Historically, this stadium produces more scoring in 2H under lights.

Player props pulled from: Consensus books | Updated: 1:00 PM ET

• Caleb Williams — Completions Over 22.5 (~even)
• Christian McCaffrey — Rushing Yards Over 87.5 (~-120)
• Jaxon Smith-Njigba — Receptions Over 4.5
• Anytime TD: D.J. Moore — (+140)
• Combined Sacks — Over 5.5

LIVE TRIGGERS TO WATCH:

• If 49ers go down early → 2H OVER, pace spikes and market chases comeback.
• If Bears 1H lead → Live 49ers ML at -120 or better; Shanahan adjusts well out of halftime.

Must-Start: Christian McCaffrey, D.J. Moore Must Fade: Bears RBs outside Herbert, 49ers backup WRs Deep DFS dart: Bears TE Cole Kmet (red zone usage up in primetime)

Strong edge for the 49ers at home — veteran experience and second-half adjustments should wear on the Bears rookie QB and the fatigue-prone Chicago defense. Expect play-action and misdirection to be the separators late.Pick: San Francisco 49ers -4.5 (Best bet pre-kick, look for live value if Bears go up early) Total: Lean OVER 48 Projected Score: 49ers 31, Bears 20 For 2H plays, alternate totals, and live prop adjustments, visit HandicappersHideaway.com — home of The Hideaway Hot Sheet.
