Do I have drop

I am a 15 year old boy who just one day got back from soccer practice one day, sat down, and two hours later I couldnt move my right foot upwards.
I didn’t have any injuries.
I don’t think I damaged any nerves.
I just want to know y I can’t move my foot.
It dosnt hurt, but when I touch it I feel it, so I don’t think it is dumb.
When I walk I have to like “flop” it.
It is really weird and came outta nowhere.
