We examine how mixing between the Standard Model Higgs boson, $h$, and theradion present in the Randall-Sundrum model of localized gravity modifies theexpected properties of the Higgs boson. In particular, we demonstrate that thetotal and partial decay widths of the Higgs, as well as the $h\to gg$ branchingfraction, can be substantially altered from their Standard Model expectations.The remaining branching fractions are modified less than $\lsim 5%$ for most ofthe parameter space volume.Comment: 17 pages, 7 figs., LaTex; revised versio
