Left my xbox game in xbox

I got my xbox as a birthday/christmas present which was really big for me, and when I got it I also got my favorite game madden with it. When the pacakge arrived there was something wrong with the hdmi port so I sent it back to microsoft and they gave me a new xbox. However I accidentaly left madden in my xbox that I first got and it is the only game I have and I would like to know if there is any way I could possibly get it back?
