Joe Flacco would like to clear something up with everyone: He's not dead.

For the second time in three weeks, Twitter tried to kill off someone in the NFL, and this time around it was Flacco.

Around 9 p.m. on Wednesday, a Baltimore Ravens fan account (not affiliated with the team) tweeted out some horrible news about Flacco.

Despite what the tweet says, Flacco was not killed, and just to prove he's alive, the Ravens quarterback took to Twitter on Thursday and sent out his own tweet.

Spoiler alert: If you watch Game of Thrones and haven't started watching Season 6, Flacco's tweet is going to give away a huge plot line.

Anyway, Flacco is clearly caught up on Game of Thrones because after the rumor about his death, he sent out the tweet below.

That is pretty much a perfect use of Twitter.

If you don't watch Game of Thrones, that character is Jon Snow. Snow was killed at the end of Season 5 and then brought back to life in Season 6.

The Ravens also sent out a Tweet, but it wasn't as amusing as Flacco's.

I do like that hashtag though, even if I don't practice it. I believe pretty much everything I read on Twitter.

Flacco's "death" comes less than three weeks after the same thing happened to Roger Goodell. Back in early June, a hacker took over the NFL's official Twitter account and announced that Goodell had died, even though the NFL commissioner was very much alive at the time, and still is.
