Gears not engaging, after being rough with the gear shifter.

Does this sound like something minor (maybe something slipped/loose inside) or am I looking at a bigger teardown? Any pointers before I crack it open would be hugely appreciated.

So now the bike starts up and runs 'normally', but seems to be stuck in gear?
what happens now when you go to change gear?

If it's a trans problem then it's engine out, roll over and remove bottom crankcase in any case I'm afraid.
But remove sump before taking engine out the bike, to be sure any broken bits are removed before rolling engine over in case they fall down (upwards) into upper engine.

I can't move the shifter pedal at all, with or without clutch. even I tried with the hands.

I know the bolt that loosens can cause either a floppy or completely jammed shifter.
but could be a number of things, dislocated and broken gears, broken shift fork, etc.

Only way to know is to open it up I'm afraid
