J.K. Rowling is a Seahawks fan.

The author of the Harry Potter series tweeted about her fandom a day after Richard Sherman dressed up as Harry during a news conference.

In true Halloween spirit, Sherman wore his Harry Potter best, with wand in hand, to Wednesday’s news conference.

“When you’re a wizard, like we are out here, sometimes you have to show it to the Muggles out in the world," he said.
