If he size of the rock you found can fit inside your hand, then you should consider that somebody is trying to sabotage your ride
If it was as big as nail, then it can happen.
However, don't cut or remove your drain tube. This is almost like an 1-way valve. It lets water to come out of the airbox (considerably faster when you squeeze it form the outside) but doesn't really let it in. It needs periodic cleaning on the inside from the small stones. leaves, etc. that are finding their way in.
If you do, then more water and debris will find its way into the airbox
