Son Heung-min was passed fit for South Korea to start their World Cup opener against Uruguay at Education City Stadium on Thursday.
The Tottenham forward fractured an eye socket in the Champions League game against Marseille on November 1 and donned a facemask to take on the South Americans.
His availability was a big boost for coach Paulo Bento as the Koreans looked to get their Group H campaign off to a winning start.
Son entered the game one goal short of becoming South Korea's joint-top World Cup goalscorer and only the second player from the country to score in three separate World Cups after Park Ji-sung, who netted once in each of the 2002, 2006 and 2010 tournaments.
Uruguay started the game with a front two of Darwin Nunez and Luis Suarez, with Edinson Cavani still struggling to shake off an ankle injury.
