The Denver Broncos waived wide receiver KJ Hamler with a non-football illness designation on Monday. The 24-year-old receiver explained his health situation in a post on Instagram:

After feeling some chest pains while working out on the break before camp started, I got everything checked out and was diagnosed with mild heart irritation, called pericarditis. I’ve got a great treatment plan with medicine and am taking a quick break to get this all taken care of so I can get back to doing what I love.

I’m so grateful for my teammates & coaches. Appreciate the support from the Broncos Country and encouragement I have been receiving. This is something to bring awareness to anybody. So anyone with chest pains please get checked out by your doctor!

24 years old, way too late for a heart defect from birth to be discovered. We're going to be seeing a lot more of this.

The really fucked up part is they consider this to be 'not football related' so he can't get any medical bills paid despite the NFL forcing him to take the shot.
