We present lattice results on the scalar $D_s$ meson and comment on the $D_{\mathrm{sJ}}^{+}\mathrm{}\left(2317\right)\mathrm{}$ state recently discovered by BaBar and confirmed by CLEO, in view of a series of theoretical claims and counterclaims. Lattice predictions in the static limit indicate larger masses than observed for a scalar quark model state. Finite c quark mass corrections seem to further enlarge this discrepancy, in support of a non-quark-antiquark-state interpretation of experiment.
