There is a fake free agent player, Sabrina Ladha, a goalie with a 98 OVR rating. To make sure she does not end up playing for another team in your Dynasty or Be A Pro mode, use the "Edit Player" feature in the creation zone. Get to the free agents and go down to "S. LADHA". Edit her ratings down to "50" on everything. This will ensure that nobody signs her. Alternately, choose to sign her to a team that you will not be using or playing against, such as like a European or National team.
