  $d^\ast(2380)$ was observed by WASA-at-COSY collaborations in the nuclear
reaction recently. Its particularly narrow width may indicate the new
QCD-allowed hadronic structure. To further confirm the existence of this
peculiar particle in a totally different kind of reaction, we study the
opportunity for searching $\bar{d}^\ast$ in the $\Upsilon(nS)$ (with n=1, 2, 3)
decay. As a phenomenological study, our framework is based on SU(3) chiral
quark model. By virtue of the unitarity of $S$-matrix and crossing symmetry, we
study the imaginary part of the forward scattering amplitudes between
$\Upsilon(nS)$ and $d^\ast$. The scattering process is mainly governed by the
quark-meson interaction. We examine both the pseudoscalar and vector meson
contribution in the intermediate state. Hopefully, our results show that it's
quite possible to find $\bar{d}^\ast$ in this decay mode in the future.
