In the present paper we investigate the question about the injectivity of the map $\f(R) \ra \f(K)$ induced by the canonical inclusion of a local regular ring of geometric type $R$ to its field of fractions $K$ for a homotopy invariant functor $\f$ with transfers satisfying some additional properties. As an application we get the proof of Special Unitary Case of Grothendieck's conjecture about principal homogeneous spaces and some other interesting examples.
