We combine four measurements of the forward-backward charge asymmetry $A_{FB} $ in
$p\bar{p}\rightarrow Z/\gamma^{*} \rightarrow e^+ e^-/\mu^+\mu^- + X$ events using $\sim 10\ $fb$^{-1}$ of $ p\bar p$ data collected at $\sqrt s=1.96\ $TeV by the CDF and D0 detectors at the Fermilab Tevatron collider. $A_{FB}$ is measured as a function of the invariant mass of the dilepton system to extract the effective weak mixing angle $\sin^2\theta^{lep}_{eff}$. We discuss the combination of these measurements and present the indirect extraction of the W mass in the context of the standard model.
