Have you ever seen chain damage like this?

Hello fellow FZ/MT riders, I was adjusting my chain and noticed one of the rollers has a section missing... what's strange is the part of the roller that remains rotates freely on the pin, and snugly, just like the ones that aren't damaged. In other words it's not bent or stretched out of shape, it just has a section missing. Have you ever seen a chain with this sort of wear/damage? BTW, the chain and sprockets have about 17k miles on them.

Just ordered another chain/sprockets, but I have a ride planned for tomorrow. What I don't know is how compromised the strength of the chain may be, and I realize different people have different tolerances for risk, but would you ride the bike with the chain in this condition?

Maybe a little hard pebble got lodged in the chain and cracked the roller when wedged between chain and sprocket? Had that a couple of times on my off-road bike when riding.... engaged... over gravel surfaces.
Might want to check sprocket(s) for corresponding damage.
Agree with the previous comments - chain and sprockets should definitely be replaced!
