Valdes-Scantling had one reception for nine yards in Sunday's 16-15 win over Arizona.
Valdes-Scantling finally recorded his first catch as a member of the 49ers after posting bagels in his first two appearances. The 30-year-old was on the field for 17 snaps (26 percent) and finished behind Ricky Pearsall, Kendrick Bourne and Skyy Moore in terms of playing time and production. With San Francisco expecting reinforcements to the receiver room Week 4, Valdes-Scantling may find his marginal role on offense reduced further.
