Based on the t-J model and the self-consistent Born approximation, the damping of quasiparticle hole states near the Fermi surface is calculated in a low-doping regime. Renormalization of spin-wave excitations due to hole doping is taken into account. The damping is shown to be described by a familiar form Im{Sigma}({bold k}{sup {prime}},{var_epsilon}){proportional_to}({var_epsilon}{sup 2}/{var_epsilon}{sub F})ln({var_epsilon}/{var_epsilon}{sub F}) characteristic of the two-dimensional Fermi liquid, in contrast with the earlier statement reported by Li and Gong [Phys. Rev. B {bold 51}, 6343 (1995)] on the marginal Fermi-liquid behavior of quasiholes. {copyright} {ital 1997} {ital The American Physical Society}
