LaTeX, 9 pages, 1 figure - published version<br/>We analyze the recently discovered $D_{sJ}(2860)$ meson using arguments based on the heavy quark expansion together with the experimental observations. We consider the possible quantum number assignments, arguing that the interpretation of the meson as the $J^P=3^-$ $c \bar s$ state is favoured.<br/>
