Manchester United youngster Dean Henderson allowed a 50-yard back-pass from Chelsea’s Fikayo Tomori to slip past him at the U20 World Cup.
The Red Devils goalkeeper was turning out for England in a group stage meeting with Guinea.
England held a narrow one-goal lead shortly before the hour mark, but saw that advantage cancelled out in comical fashion.
Tomori didn't check on the positioning of his keeper before firing the ball in his direction, leaving Henderson wrong-footed and unable to prevent a remarkable own goal.
The nightmare moment ended up costing England two points, as they were held to a 1-1 draw.
Paul Simpson’s side are, however, still top of Group A after their opening two fixtures – having previously beaten Argentina 3-0 in their opening contest.
Next up for England's Under-20s will be a final group game against South Korea on Friday.
