Is it ok to wait 2-3 weeks between getting an extraction, and getting a Bone Graft?

I have a tooth, #19, that is going to be extracted wednesday. I know that I need a dental implant and a bone graft first, but I need to wait a couple of weeks between extracting the tooth and getting the graft. Primarily because the I can't get the extraction done in my regular office prior to my vacation next week. The tooth has cracked and half has fallen off. It was the result of a poorly placed cavity which lead to a cavity underneath the filling.
