I did that once. Well, more than once.
Scrubbed them clean, then threw them on the rack alongside something else I was baking. Took dinner out, turned the oven off, and planned to leave the potatoes in to finish baking with the residual heat. Remembered them when I went to get them out of the refrigerator for the next evening's dinner. Used them, ate them, we're both alive. Never did get as much as a burp from them. That was our experience. You might have a different one, so use at your own risk.
