Signed psych prematch and now a BETTER offer???? - yellowfever

[ArchivalUser]

hello ever1, i signed a prematch at a hospital in NY (psychiatry) 2 weeks ago and 2day all of a sudden i got a call from another hospital in NJ about prematch offer..

actually the NJ hospital i ived was BEFORE the NY hospital where i signed the prematch. Is it possible i can cancel my prematch and sign the new prematch?? where can i find rules about this??

thanks
