[Jack In The Box]

I have a very important question. I had one of my teammates get injured a couple of days ago, and his injury is going to keep him out of this event. I need to know how I go about changing/adding a different person to my roster. I need to know if I even can do that. I have sent an email to the event coordinator explaining this, however, I want to make sure this is all I need to do.

Thank you very much.

EDIT: Already got it approved. Thanks again.
