A non-relativistic quark model has been used in the calculation of the K-pole contributions to s-wave amplitudes for non-leptonic decays of hyperons, which involve usd\rm\bar K\sp{*0}-\pi\sp0usd and K weak transitions. Such corrections were thought to be one way of removing the long standing discrepancy between s- and p-wave amplitudes obtained in the current-algebra approach to non-leptonic decays of hyperons. Although the calculation of the K contribution on the quark model is found to be negligible, it gives the right order of magnitude of small observed deviations from the usd\DeltausdI = 1/2 rule. A comparison of the observed deviation from usd\DeltausdI = 1/2 rule for s-wave hyperon decay amplitudes with estimated ones is discussed.
