NEW YORK (AP) The NFL is looking into how its Twitter account came to be hacked with a post purporting that Commissioner Roger Goodell had died.

Around midday Tuesday, a post went up on the league's official account that read: ''We regret to inform our fans that our commissioner, Roger Goodell, has passed away. He was 57,'' followed by a hashtag and ''RIP.''

That tweet was soon deleted, as were follow-up tweets that said: ''Oi, I said Roger Goodell has died. Don't delete that tweet,'' and, as other Twitter users surmised it was a hack, ''OK, OK, you amateur detective win. Good job.''
