We consider mappings satisfying the Poletsky-type inverse inequality in a domain of the Euclidean space. It is shown that the uniform limit of the family of these mappings is a discrete mapping. We separately consider domains that are locally connected on their boundaries and regular domains in the quasiconformal sense.
