Commutant Lifting for Commuting Row Contractions

If $T=\left[T_1\mathrm{.}\mathrm{.}\mathrm{.}{T}_n\right]$ is a row contraction with commuting entries, and the Arveson dilation is $\tilde{T}=\left[{\tilde{T}}_1\mathrm{.}\mathrm{.}\mathrm{.}{\tilde{T}}_n\right]$, then any operator $X$ commuting with each $T_i$ dilates to an operator $Z$ of the same norm which commutes with each ${\tilde{T}}_i$.
