The tweet, which was deleted minutes after it was posted, said "We regret to inform our fans that our commissioner, Roger Goodell, has passed away. He was 57. #RIP"
Brian McCarthy, the league's vice president of communications, confirmed on his owner Twitter page that the league's account was hacked and said that Goodell "is alive and well."
Shortly after the original tweet about Goodell was deleted from the league's official account, two other tweets the league said didn't come from their office were posted on the page. Those tweets also were deleted.
