The Seahawks had a rare in-season weekend without a game after having beaten the San Francisco 49ers Thursday night.
Quarterback Russell Wilson apparently spent the time off celebrating girlfriend Ciara's 30th birthday. It was a superhero-themed party, and the guest list included Beyonce.
Wilson and Ciara dressed up as Batman and Catwoman. Wilson posted photos from the night, along with the Batmobile, on his Instagram account.
If Wilson shows up to practice today in this costume, we're guessing Michael Bennett and a few other teammates might have a thing or two to say to him.
