Abstract: Let $ \Gamma $ be a finite, undirected, connected graph and G a subgroup of $ {\operatorname{aut}}(\Gamma )$ acting transitively on the vertex set of $ \Gamma $ such that the stabilizer $ G(x)$ in G of a vertex x contains a normal subgroup which induces a permutation group on the set of vertices adjacent to x isomorphic to $ PSL(n,q)$ with $ n \geqslant 3$. A bound for $ \vert G(x)\vert$ depending only on n and q is shown to exist under certain conditions.
