We prove that for any finite tournament and any of its partial automorphisms there exists a finite extension of the original tournament in which this partial automorphism can be extended to a complete automorphism. An estimate for the size of this extension is given. Furthermore, it is proved that every finite tournament has a finite transitive extension, and the order of this extension is specified.
