Scotland’s 43-year-old goalkeeper Craig Gordon announced his retirement from soccer Thursday after being the oldest among more than 1,250 players picked for the World Cup. “It has been a privilege to represent you,” Gordon, the Heart of Midlothian and former Celtic and Sunderland goalie, said in a video message on social media. Gordon did not play at the World Cup as backup in three group games to Angus Gunn, who last week joined San Jose Earthquakes in Major League Soccer.
