  We give a new cyclic sieving phenomenon for semistandard Young tableaux
$SSYT(\lambda,\mu)$ of shape $\lambda=(m,n^b)$ and content $\mu$, a
$(b+2)$-tuple. We prove that $(SSYT(\lambda,\mu),\langle \partial^{b+2}
\rangle, f(q))$ exhibits the cyclic sieving phenomenon, where $\partial$ is the
jeu de taquin promotion operator and $f(q)$ is a modified Kostka-Foulkes
polynomial $\widetilde{K}_{\lambda,\mu}(q)$, up to a power of $q$.
