We discuss how mixing between the Standard Model Higgs boson, h, and the radion of the Randall-Sundrum model can lead to significant shifts in the expected properties of the Higgs boson. In particular we show that the total and partial decay widths of the Higgs, as well as the h {yields} gg branching fraction, can be substantially altered from their SM expectations, while the remaining branching fractions are modified less than {approx}< 5% for most of the parameter space volume. Precision measurements of Higgs boson properties at a Linear Collider are shown to probe a large region of the Randall-Sundrum model parameter space.
