Second time homebrew Midwest Ferocious IPA Oops!!

I am brewing my second batch of beer. My first was the Midwest Irish Dry Stout that turned out very good. I had the help of a friend the first time. This time I did everything myself. I followed the recipe through all the steps to the point where I was bringing the wort up to the 5.5 gallon mark by adding distilled water. Unfortunately, the little plastic ring that seals the cap on the water jug fell into my wort after it was cooled to 75 degrees. I was unable to fish it out with a sanitized spoon. Tonight I found it floating on top when I removed the cover from my fermentation bucket. I got it out with a sanitized spoon while adding the dry hops.
What are the chances that this will cause me contamination ? Also, the recipe recommends secondary fermentation, but all I have is the fermentation and bottling bucket. I just added the hops after soaking the bags in starsan. Will this recipe turn out okay without a secondary? I plan on bottling in 7-10 days. Thanks for any input.

 

Thanks Herb. I appreciate the advice. :-)
