It was reported that the 24-year-old Argentine had suffered a 'cardiopulmonary arrest during a workout' - but the three-time Ballon d'Or winner is alive and well
The 'news' appeared on the organisation's Norte Twitter feed and although the message was quickly deleted, it was noticed by several bemused Spanish media outlets.
“We announce the sad news that Lionel Messi died of cardiopulmonary arrest during a workout,” the tweet read.
Rumours of Messi's death were false as the three-time Ballon d'Or winner, who scored his 73rd goal of the season in Friday's Copa del Rey final win over Athletic Bilbao, remains very much alive and well.
Fox Sports have yet to reveal the reasons behind the misinformation but it is believed that their Twitter feed was hacked.
