Jets' Justin Fields Faces Uncertainty After Concussion

Imagine your brain as a soft sponge inside your head.

A concussion is like bumping your head hard, making the brain move around too fast and maybe get hurt a little.

It can cause a headache, make you dizzy, or even make it hard to think clearly.

The Jets quarterback, Justin Fields, got one during a game.

Now, he might not be able to play in the next game because doctors need to make sure he's feeling better.

Concussions can be tricky because they can affect how well your brain works for a while, so it's important to take time to heal.
