dc.descriptionIn 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.
