Let X be a Fano manifold of Picard number one different from the projective space. It has been conjectured that a surjective endomorphism X → X must be bijective. In this article, we will prove a weaker version of the conjecture: a surjective endomorphism X → X which is étale outside a completely invariant divisor is bijective. As applications of this result, the conjecture is confirmed in the case where the variety of minimal rational tangents of X is linear and in the case where X is quasi-homogeneous.
