  In a recent Letter Balatsky and Salkola made their conclusion about the
absence of localization in disordered d-wave superconductors exploiting the
idea that strongly overlapping impurity states formed a network capable to
provide the transport. We present here the correct estimate of hopping matrix
elements between two impurities which were the basic quantities for the
subsequent consideration in the abovementioned Letter. We conclude, that the
picture of the impurity-impurity potential acting only within the slowly
broadening tails claimed by Balatsky and Salkola as well as all the physical
consequences of this picture appear to be incorrect.
