What started out as a slave cylinder issue has now gone to a broken clutch fork.

Background: got in the car to go to work, shift into 1st no problem, push clutch pedal in to go into neutral and pedal goes to the floor and stays there. Previous day car ran fine, no noises and/or vibrations. Just out of the blue the problem shows up and frankly I am at a loss to explain it.
So far it covered under warranty but now the Toyota rep needs to make a determination as to whether the car has been abused or not. This car has been babied and in no way abused. Hopefully everything gets covered under warranty.
Anyone else experience this problem?
