Russia's Yerokhin becomes first 'fourth sub' at World Cup

MOSCOW (Reuters) - Russia's Aleksandr Yerokhin made a little piece of World Cup history on Sunday when he became the first man to appear as a fourth substitute in a tournament match during the hosts' game against Spain in Moscow. FIFA introduced a new regulation for the 2018 World Cup that allowed teams to use a fourth replacement in extra time, and coach Stanislav Cherchesov took advantage of it halfway through the first period, sending on Yerokhin for Daler Kuzyayev. The game was level at 1-1 after 90 minutes and also at the point of the fourth change. (Reporting by Mitch Phillips; Editing by Hugh Lawson)
