Khawaja's Fitness in Doubt for Gabba Test

Usman Khawaja, a key player for Australia, hurt his back during a recent cricket match.

With only a few days left before the next important match at the Gabba, doctors and coaches are closely watching his training to see if he can play.

Khawaja did some practice runs and batting, but he didn't look completely comfortable.

The team will decide if he's ready to play after seeing how he feels the next day.

If he can't play, two other players, Beau Webster and Josh Inglis, might take his place.

Meanwhile, the team's captain, Pat Cummins, who also had a back injury, is practicing hard to possibly return for a later match.
