I have to be cautious, have my thyroid levels checked, and as long as I do that, I'm fine.

I was diagnosed with Graves' disease, an illness of the thyroid gland. Instead of surgery, I was given radiation treatment.

I don't have a thyroid anymore. I had radioactive iodine treatment, which destroyed my thyroid. I take medication every day.

While receiving radiation treatment for a thyroid illness, I had refused to take beta-blockers - a medication that would have eased its side effects - because they were deemed illegal by the sport's governing body, the International Association of Athletics Federations.

He's doing fine. But we're going to continue to be cautious.

I'm sure he'll be fine. It's just bruised. I wanted to be cautious.
