Clutch pedal stuck and car wouldn't start on 2005 Nissan Altima

When I got off a traffic light and tried to shift gears heard some breaking sound and the clutch got stuck and it wouldn't come out but I am able to press it all the way down ..... Had to tow the car back home as car wouldn't start .... Looks like the clutch pedal assembly seems to be broken ... i say the assembly is broken because the clutch pedal in out motion is not normal, it dangles sideways ....any idea why this would happen

Have you gotten under the dash yet to VISUALLY inspect? Maybe just retainer 'pin' came off allowing the pedal to slide off pushrod?
