Using three point QCD sum rule methods, the form factors relevant to semileptonic Bs→DsJ(2460)ℓν decay are calculated. The q2 dependences of these form factors are evaluated and compared with the heavy quark effective theory predictions. The dependence of the asymmetry parameter α, characterizing the polarization of the DsJ meson, on q2 is studied. The branching ratio of this decay is also estimated, and it is shown that it can easily be detected at LHC.
