Wayne Rooney has been credited with England's second goal against Switzerland after a meeting of Uefa's technical committee.
Video replays showed that Rooney's shot hit the post and went in off the back of Swiss keeper Jorg Stiel's head.
But Uefa spokesman Rob Faulkner said: "The original shot was on target so we confirm that Rooney is the scorer."
Rooney had already become the youngest scorer in European Championship finals history with a first-half header.
The Everton forward said of his second goal in the 3-0 victory: "I hit it as hard as I could and luckily it went in. I am going to claim it."
The decision means Rooney joins Sweden's Henrik Larsson and Frenchman Zinedine Zidane as joint top scorers on two goals.
OFFICIAL UEFA RULING
Shots which are on target but are then deflected, or balls rebounding off the goal frame and hitting a defender or goalkeeper, will not be considered as own goals
The Uefa committee includes former Scotland coach Andy Roxburgh, ex-Liverpool boss Gerard Houllier as well as former Switzerland
chief Roy Hodgson.
Uefa communications director William Gaillard also said it would stand by the decision to rule France's first goal against Croatia an Igor Tudor own goal.
England coach Sven-Goran Eriksson had earlier said he was hopeful Uefa would not to take the goal away from Rooney.
"I don't know how Uefa look at these things but it would be a pity if it's an own goal," said Eriksson.
"He did everything and I hope the goal is his.
"He is a fantastic talent. He played very well against France and scored two this time, one more beautiful than the other.
"I hope he goes on like that for the rest of the tournament and after it.
"I think he'll be even better in the future. He can improve still, I'm sure
Eriksson was also pleased with the manner in which his side responded to their defeat by the French in the opening game.
"When you lose as we did on Sunday you never know what the reaction will be," he added.
"I thought the reaction would be very good - and it was. We were nervous at the beginning, it was difficult to keep the ball.
"But we've done the job and the three points are the most important thing.
"The heat affected both teams but I'm happy because our fitness level is much better than it was in the World Cup in 2002."
Rooney said the result had lifted a weight off England's shoulders after their opening game defeat.
"It was a big day for us and we came through in the end. It wasn't the best performance but when the Swiss had a man sent off we took advantage," he admitted.
"It's a relief after the France game. We're back on track now and we've got to go on and win the next match."
Of his goals, the Everton striker added: "For the first one, Michael Owen put it right on my head and for the second I just hit it hard enough and luckily enough it went in."
