The eikonal approximation is used to investigate the forward one-fermion matrix element of the bilocal operator that appears in the most singular term of the canonical~ light-cone current commutators for the fermion-neutral-vector- gluon model. A relationship is exhibited between this matrix element of the bilocal operator and the leading behavior of nu W2. This relation allows calculations of contributions to the matrix element of the bilocal operator to be applied to the corresponding contribution to nu W2. A simple set of graphs contributing to the matrix element of the bilocal operator is calculated in the eikonal approximation. This gives a contribution to nu W2 in agreement with explicit calculations in perturbation theory for the corresponding set of graphs of nu W2. (auth)
