Let $W$ be a Coxeter group acting properly discontinuously and cocompactly on manifolds $N$ and $M\ ({\partial }M = {\emptyset })$ such that the fixed point sets of finite subgroups are contractible. Let $f: (N, {\partial }N) \to (M{\times }D^k, M{\times }S^{k-1})$ be a $W$-homotopy equivalence which restricts to a $W$-homeomorphism on the boundary. Under an assumption on the three dimensional fixed point sets, we show that then $f$ is $W$-homotopic to a $W$-homeomorphism.
