  We present preliminary results from our analysis of the form factors for the
$\overline{B}\rightarrow D^\ast\ell\overline{\nu}$ decay at non-zero recoil.
Our analysis includes 15 MILC asqtad ensembles with $N_f=2+1$ flavors of sea
quarks and lattice spacings ranging from $a\approx 0.15$ fm down to $0.045$ fm.
The valence light quarks employ the asqtad action, whereas the heavy quarks are
treated using the Fermilab action. We conclude with a discussion of future
plans and phenomenological implications. When combined with experimental
measurements of the decay rate, our calculation will enable a determination of
the CKM matrix element $|V_{cb}|$.
