It seems like you really want an interview/tour/practice drop-in visit along the lines of a RL corporate job interview to happen (which would have made this question a lot easier to deal with if you'd insisted on that to begin with). In which case, an interview or tour type thing is very much a possibility, assuming the player doesn't have his rights held by any other club or has been given permission to talk to other clubs. But the practice drop-in or scrimmage or other participation in club activities is something I've never once heard of happening before an agreement of some kind has been signed, and then once it's been signed, I've never heard of it being anything but a full-on "you're a part of this team until we cut/waive/release/send you down" type of thing.
