If you are heading to Capital One Arena to see the Eagles tonight and tomorrow you will have to prove that you have been vaccinated against COVID-19. Some venues allow you to simply flash your vaccination card, or even display a picture of your vaccine card on your phone. However, Capital One Area has informed guests they will only be accepting proof of vaccine via the Clear mobile app. You have to download the app ahead of time and upload your vaccination card. Not vaccinated? You can still attend but you'll have to upload proof of a negative COVID-19 test taken within the last 24 hours, or proof of antigens. All the info you need is here on the Monumental Sports website.
