Pat Cummins Uncertain for Ashes Opener Due to Injury

Australia's cricket captain, Pat Cummins, might not play in the first big match called the Ashes.

He has a back injury called lumbar bone stress.

This means there's a little problem with his bones.

He had a scan that wasn't too bad, but he needs to be careful.

He's not playing in some other games right now.

Doctors are watching his back closely so he can get better.

The Ashes is a very important competition, and everyone wants to see if he will be healthy in time to play.
