Abstract
We reexamine the cancellation of infrared divergences in massive quark potential scattering in a non-Abelian gauge theory. We improve on previous arguments and extend the proof of cancellation to cases of gauge-nonsinglet potentials and quarks of specific color. We also observe that cancellation fails in the case of the scattering of quarks of specific color by a nonsinglet potential.
