The boxing medical form should be available from the club.

I don't mean to worry you, but if the club did not distribute sparring forms then they probably haven't been covered by any health and safety laws up until this point.
It went into legislation before the initiation of last years European season that all boxers should be medically checked and ABA (or in my case IABA) carded before participating in sparring matches.
Check that out.

And if the club doesn't have any perhaps attend yourself to see how the club is run.
