I think you are going to be okay. How long has the beer been in the fermenter? You've got to go a really long time before you've got a problem. Most people here will tell you three weeks is pretty close to a minimum and you can go a lot longer than that until autolysis is a problem.
I've heard from 2 brewers who left their brew in the primary for something like 8 months without a problem. Your extra 2 weeks just counts toward maturing the beer.
