The ball bounced off the Brazilian's palms and looped towards goal, but Stones reacted quickly to retreat and make a diving clearance that only just saved his side.
Indeed, on first glance it looked every inch a goal but the reality was even closer than that.
After reviewing the decision, the Premier League's goal review system showed that over 95% of the ball had crossed the line - but not all of it as would be necessary to award the goal.
Stones went from near-zero to absolute hero in a matter of seconds and Ederson, who initially made a mistake to concede the chance, was saved from an embarrassing own goal.
