  Using the results of the recently studied problem of adsorption of a Gaussian
polymer in a weak periodic surface potential we study the influence of a single
rod like defect on the polymer being localized in the periodic surface
potential. We have found that the polymer will be localized at the defect under
condition u>u_c, where u_c is the localization threshold in the periodic
potential, for any infinitesimal strength of the interaction with defect. We
predict that the concentration of monomers of the localized polymer decays
exponentially as a function of the distance to the defect and is modulated with
the period of the surface potential.
