Anode cap question -- came out during move

Picked up a cab today and like an idiot I left the carts in not even thinking about them coming loose and hitting stuff inside the cab. Lesson learned. Anyway, the anode cap popped out of the monitor and I want to know if it is safe to just put it back in.

edit: apparently it is safe to just put it back in or I am just lucky. Regardless, montor is up and operational now and I am a happy guy.
