Seahawks rookie RB Zach Charbonnet had a tough game against the 49ers in Week 12, with limited rushing yards and receptions. The Seahawks' offense struggled in the first half, and QB Geno Smith's injury affected their performance. The 49ers' run defense has been strong recently, not allowing over 100 rushing yards in four out of their last five games. Charbonnet's upcoming schedule is also challenging, with tough matchups against the Cowboys and 49ers again.
