Abstract: Let $ M$ be a complete $ n$-dimensional submanifold in the $ (2n - 1)$-dimensional Euclidean space, with scalar curvature bounded from below. Baikousis and Koufogiorgos proved that the sectional curvature of $ M$ satisfies sup $ {K_M} \geqslant {\lambda ^{ - 2}}$ if $ M$ is contained in a ball of radius $ \lambda $. We extend this result to the case that the ambient space is a complete simply connected Riemannian manifold of nonpositive curvature.
