Wilson was injured with about 10 minutes to go in the third quarter getting pulled down awkwardly on a sack by San Francisco's Eli Harold. Harold was called for a horse collar penalty, but the bigger concern was how he fell on Wilson's left leg.
Wilson stayed down on the field for a few moments before walking off. Wilson missed the first play of his career due to injury, but returned to throw one more pass. The completion led to the third of Steven Hauschka's three field goals for a 27-3 lead and after that Wilson's day was done.
Wilson had a brace placed on his left knee, and he never saw the field again, giving the final 1 ½ quarters of the blowout to rookie Trevone Boykin.
Baldwin had eight catches for a career-high 164 yards.
Getting the start with Thomas Rawls out because of a shin injury, Michael had TD runs of 41 and 4 yards on Seattle's first two drives. Michael rushed for 106 yards on 20 carries, the second 100-yard game of his career.
