The Twitter account for the National Football League (NFL) announced and quickly deleted a tweet suggesting that commissioner Roger Goodell had died.
Boasting 19.2m followers, the hacked account announced the hoax death to a large audience, although the tweet was only live for a short time and appeared to fool very few people.
The association confirmed that a hack had occurred and that the 57 year was indeed not dead.
The offending tweet read: "We regret to inform our fans that our commissioner, Roger Goodell, has passed away. He was 57. #RIP."
The hacker had control of the account for a brief window on Tuesday evening (7 June).
The prank comes after the accounts of Facebook founder Mark Zuckerberg were also compromised days earlier.
