  Recently Babar Collaboration reported a new $c\bar{s}$ state $D_{sJ}(2860)$
and Belle Collaboration observed $D_{sJ}(2715)$. We investigate the strong
decays of the excited $c\bar{s}$ states using the $^{3}P_{0}$ model. After
comparing the theoretical decay widths and decay patterns with the available
experimental data, we tend to conclude: (1) $D_{sJ}(2715)$ is probably the
$1^{-}(1^{3}D_{1})$ $c\bar{s}$ state although the $1^{-}(2^{3}S_{1})$
assignment is not completely excluded; (2) $D_{sJ}(2860)$ seems unlikely to be
the $1^{-}(2^{3}S_{1})$ and $1^{-}(1^{3}D_{1})$ candidate; (3) $D_{sJ}(2860)$
as either a $0^{+}(2^{3}P_{0})$ or $3^{-}(1^{3}D_{3})$ $c\bar{s}$ state is
consistent with the experimental data; (4) experimental search of
$D_{sJ}(2860)$ in the channels $D_s\eta$, $DK^{*}$, $D^{*}K$ and
$D_{s}^{*}\eta$ will be crucial to distinguish the above two possibilities.
