Time remains of the essence for crews working to rescue Thailand's trapped football team.

Eight boys have been rescued from the cave and are in hospital.

But four boys and their coach are spending another night trapped deep underground.

CNN's Matt Rivers told Larry Williams rescuers may have just one more day left to the get them out.

"It's going to rain and it's going to rain a lot, that is expected, the forecast is showing more rain and so you can expect rescuers to really try6 and wrap this rescue up."

The search has been suspended for the night.
