The present investigation suggests that a weakly bound state for the $\\bar{K}\\bar{K}N$ system can be formed below the two-body threshold of $\\bar{K}$ and quasibound $\\bar{K}N$ with a $40 \\sim 60$ MeV decay width of $\\bar{K}\\bar{K}N\\to \\pi Y\\bar{K}$. This corresponds to an excited $\\Xi$ baryon with $J^P=1/2^+$ located around 1.9 GeV.
